HighPrep PCR Beads vs. AMPure XP: 3 Reasons to Make the Switch

When it comes to PCR cleanup in next-generation sequencing (NGS) workflows, SPRI bead-based purification remains the gold standard. For years, AMPure XP has dominated the market with its reliable but expensive solution. However, labs are now increasingly turning to a smarter alternative—MagBio Genomics' HighPrep PCR beads.

Why are more researchers switching from AMPure XP to HighPrep PCR? Because they want better value, equal (or better) performance, and true workflow flexibility. In this article, we dive into the top three reasons why HighPrep PCR has become the preferred choice for DNA purification—and why it might be time for your lab to make the switch.

Reason 1: Cost-Efficiency Without Performance Compromise

One of the biggest drivers for labs to reconsider their reagent suppliers is cost. AMPure XP is known for high recovery rates and reproducibility, but its cost per reaction adds up fast—especially for high-throughput facilities. HighPrep PCR offers a cost savings of up to 40% per sample, without compromising yield or quality.

Side-by-side tests show:

DNA recovery from 100 bp to 2 kb is nearly identical for both products.

HighPrep PCR performs equally well in removing primers, dimers, and enzymes.

Labs switching to HighPrep PCR report equivalent sequencing coverage and fidelity.

Over the course of a year, switching to HighPrep PCR can lead to tens of thousands of dollars in savings for mid-to-large-scale labs. For academic labs, that translates into more samples processed, more grant deliverables achieved, and more experiments completed on time.

By reducing per-sample purification costs, labs using HighPrep PCR can reallocate budget toward additional experiments, new equipment, or expanded sample sizes.

Reason 2: Reliable, Consistent Performance Across Applications

Whether you're doing amplicon sequencing, library preparation, or qPCR cleanup, consistency matters. HighPrep PCR beads are manufactured under strict quality controls to ensure batch-to-batch reproducibility. Unlike some generic alternatives, HighPrep PCR has gone through rigorous testing to meet the needs of sensitive molecular biology workflows.

HighPrep PCR is validated for:

Illumina and Ion Torrent library prep workflows

Post-PCR cleanup for qPCR and Sanger sequencing

Adapter dimer cleanup after ligation

Double-sided size selection protocols for fragment tuning

Automation with KingFisher, Tecan, and Hamilton platforms

In fact, one high-throughput genomics core saw a 10% improvement in recovery reproducibility after switching from AMPure XP to HighPrep PCR. The magnetic bead suspension in HighPrep remains uniform and pipetting-friendly, reducing technical variability between users and across runs.

For long-term experiments that demand reproducible input DNA, this level of consistency translates directly into higher confidence in downstream data.

Scientists have extracted RNA from an extinct species for the first time!!

They extracted it from a mummified Thylacine (Tasmanian Tiger) that was stored in Stockholm.

Just 2 months after the Thylacine was granted a protection status, the last of its kind passed from exposure in 1936 at the Beaumaris Zoo in Hobart.

It was the world's largest carnivorous marsupial, estimated to stand as tall as 51 inches and weighing around 66lb.

I'm very excited for the potential of bringing this species back - Jurassic Park style. We hunted this creature to extinction and now we may be able to fix that.

I'm so fucking exhausted guys, physically and emotionally.

But I still need to go to lab because I have an experiment schedule to keep *sigh*

[notagenteklabtech]

Today is my favourite day of the week; Sample Day! The day when we get to leave the lab and collect samples of the latest mutations in Redlight!

It's also my least favourite day of the week, as said samples have to be collected in Red Zones. But, sometimes we luck out and that week's zone has been cleared of hives before we arrive, so fingers crossed!

High Molecular Weight DNA Isolation: Why MagBio's Magnetic Beads are the Ultimate Ampure XP Alternative

High molecular weight (HMW) DNA isolation is a critical process in modern genomics research, especially for applications like next-generation sequencing (NGS), long-read sequencing, and genome assembly. Scientists rely on high-quality, intact DNA to ensure accurate results and reproducibility. In the quest for precision, researchers often turn to magnetic bead-based reagents for PCR clean-up and size selection to achieve superior results.

While the Ampure XP system has long been considered the gold standard for DNA purification and clean-up, MagBio’s HighPrep PCR magnetic beads have emerged as a powerful and efficient Ampure XP alternative. Designed specifically for PCR clean-up and size selection, HighPrep PCR offers significant advantages, especially for High Molecular Weight DNA Isolation, making it the go-to solution for many researchers looking to optimize their workflows.

High Molecular Weight DNA Matters

Before diving into the benefits of MagBio’s HighPrep PCR, it's important to understand why high molecular weight DNA isolation is so essential. HMW DNA refers to DNA fragments that are longer and more intact than standard DNA fragments. These long fragments are especially important in applications such as long-read sequencing, structural variant analysis, and genome assembly, where large DNA molecules provide a clearer picture of genetic architecture.

Accurate High Molecular Weight DNA Isolation ensures that DNA is not fragmented or degraded during extraction and purification. Longer DNA fragments lead to better sequencing results, more comprehensive genome coverage, and a deeper understanding of genetic complexity. To achieve these results, researchers require reliable purification systems that preserve DNA integrity and enable efficient downstream analysis.

Drawbacks of Ampure XP

While Ampure XP has served as the gold standard for PCR clean-up and DNA purification, it is not without its limitations. One of the major drawbacks is that the Ampure XP system can sometimes lead to loss of HMW DNA fragments during size selection, especially for applications where precise selection of long DNA fragments is necessary. Additionally, Ampure XP requires precise buffer-to-sample ratios to achieve optimal performance, which can complicate workflows and introduce variability.

In an era where speed and efficiency are crucial, many labs are also looking for more automation-friendly solutions that integrate smoothly with liquid handling systems. Ampure XP’s protocol can be cumbersome for high-throughput applications, making it less ideal for labs that require quick turnaround times and scalable workflows.

HighPrep PCR: The Superior Ampure XP Alternative

MagBio’s HighPrep PCR offers a powerful solution to the limitations of Ampure XP, providing superior PCR clean-up and size selection for both standard and high molecular weight DNA. This paramagnetic bead-based reagent is specifically designed for efficient DNA purification, ensuring high recovery rates and consistent fragment size selection, making it ideal for applications like NGS, cloning, and PCR clean-up.

High Recovery of Amplicons >100 bp

One of the key benefits of HighPrep PCR is its ability to achieve high recovery rates of DNA fragments, especially those greater than 100 base pairs. This feature makes it particularly useful for isolating longer DNA fragments, which is essential for applications such as long-read sequencing and HMW DNA isolation. Unlike other reagents, which may lose significant amounts of long DNA fragments, HighPrep PCR ensures maximum recovery, preserving the integrity of your DNA samples.

Efficient Size Selection for High Molecular Weight DNA

Size selection is a critical step in DNA library preparation for sequencing. HighPrep PCR’s magnetic bead-based system allows for precise and uniform size selection, ensuring that only the desired DNA fragments are retained for downstream applications. This is especially important for High Molecular Weight DNA Isolation, where preserving longer DNA fragments is key to successful sequencing.

HighPrep PCR selectively binds to DNA fragments based on the concentration of beads used in the reaction. This flexibility allows researchers to fine-tune their size selection to meet specific experimental needs, whether they are working with fragmented DNA, amplicons, or genomic DNA.

No Centrifugation Required

Traditional DNA purification methods often require time-consuming centrifugation steps, which can be prone to error and introduce variability into workflows. HighPrep PCR eliminates the need for centrifugation by using magnetic beads to bind and isolate DNA fragments. This not only streamlines the process but also reduces the risk of sample loss or contamination. For labs looking to increase throughput and efficiency, this is a major advantage.

Automation-Friendly Design

As more labs move toward high-throughput automation, having a PCR clean-up reagent that integrates seamlessly with liquid handling systems is essential. HighPrep PCR is designed with this in mind, offering compatibility with most liquid handling stations. This makes it an excellent choice for labs that need to scale up their operations without sacrificing precision or reproducibility.

Automation-friendly reagents like HighPrep PCR help reduce human error, save time, and allow for more consistent results. In contrast, Ampure XP may not always offer the same level of integration with liquid handling systems, making it less suited for high-throughput applications.

Consistent Fragment Size Distribution

Achieving uniform and consistent DNA fragment sizes is essential for reliable results, especially in applications like NGS. HighPrep PCR ensures that DNA fragments are consistently sized, leading to better library quality and more accurate sequencing data. This is particularly beneficial for researchers working with complex or degraded samples, where maintaining consistency across replicates is crucial.

"In a first-ever human clinical trial, an mRNA cancer vaccine developed at the University of Florida successfully reprogrammed patients’ immune systems to fiercely attack glioblastoma, the most aggressive and lethal brain tumor.

The results in four adult patients mirrored those in 10 pet dog patients suffering from brain tumors whose owners approved of their participation.

The discovery represents a potential new way to recruit the immune system to fight treatment-resistant cancers using an iteration of mRNA technology and lipid nanoparticles, similar to COVID-19 vaccines, but with two key differences: use of a patient’s own tumor cells to create a personalized vaccine, and a newly engineered complex delivery mechanism within the vaccine.

“Instead of us injecting single particles, we’re injecting clusters of particles that are wrapping around each other like onions,” said senior author Elias Sayour, M.D., Ph.D., a UF Health pediatric oncologist who pioneered the new vaccine, which like other immunotherapies attempts to “educate” the immune system that a tumor is foreign.

“These clusters alert the immune system in a much more profound way than single particles would.”

Among the most impressive findings was how quickly the new method spurred a vigorous immune-system response to reject the tumor, said Sayour, principal investigator at the University’s RNA Engineering Laboratory and McKnight Brain Institute investigator who led the multi-institution research team.

“In less than 48 hours, we could see these tumors shifting from what we refer to as ‘cold’—very few immune cells, very silenced immune response—to ‘hot,’ very active immune response,” he said.

“That was very surprising given how quick this happened, and what that told us is we were able to activate the early part of the immune system very rapidly against these cancers, and that’s critical to unlock the later effects of the immune response,” he explained in a video (below).

Glioblastoma is among the most devastating diagnoses, with median survival around 15 months. Current standard of care involves surgery, radiation and some combination of chemotherapy.

The new report, published May 1 in the journal Cell, is the culmination of seven years of promising studies, starting in preclinical mouse models.

In the cohort of four patients, genetic material called RNA was extracted from each patient’s own surgically removed tumor, and then messenger RNA (mRNA)—the blueprint of what is inside every cell, including tumor cells—was amplified and wrapped in the newly designed high-tech packaging of biocompatible lipid nanoparticles, to make tumor cells “look” like a dangerous virus when reinjected into the bloodstream to prompt an immune-system response.

The vaccine was personalized to each patient with a goal of getting the most out of their unique immune system...

While too early in the trial to assess the clinical effects of the vaccine, the patients either lived disease-free longer than expected or survived longer than expected. The 10 pet dogs lived a median of 4.5 months, compared with a median survival of 30-60 days typical for dogs with the condition.

The next step, with support from the Food and Drug Administration and the CureSearch for Children’s Cancer foundation, will be an expanded Phase I clinical trial to include up to 24 adult and pediatric patients to validate the findings. Once an optimal and safe dose is confirmed, an estimated 25 children would participate in Phase 2."

Amanita phalloides, the deadliest mushroom of the world

Commonly known as "death cap" internationally, this mushroom of European origin occurs now in all countries with temperate climate zones worldwide. It is particularly abundant in northern, central and eastern Europe, including Germany, where it forms an ectomycorrhiza symbiosis with broad leaf tree species.

Its similarity to edible mushroom species such as the straw mushroom and the white Caesar make it particularly dangerous. It may also be confused with the cultivated mushroom and the field or meadow mushroom, although clear distinguishing features exist.

Its deadly poison are heat-stable polycyclic oligopeptides of the amatoxin group with a lethal dose of about 0.1 mg per kg of body weight. This is equivalent to 20 to 40 grams of mushroom for an adult and 1 to 2 grams for children. The poison survives cooking, freezing and drying.

Amatoxins are highly efficient inhibitors of the RNA polymerase and disrupt gene expression in human cells. This causes nausea, vomiting and severe diarrhea about 8 to 12 hours after ingestion. At this time, the toxin has already distributed throughout the whole body and enriched in the liver, so any attempt to bind the toxin in the digestive tract is inefficient. The disruption of gene expression in the liver causes the liver cells to die and the liver to dissolve. Blood coagulation is severely disturbed, leading to severe interior bleeding. Hepathic encephalopathy leading to coma is the final cause of death and occurs six to ten days after ingestion.

Early stages or a mild poisoning is treated with Silymarin, an extract from the milk thistle, which inhibits the uptake of amatoxins into the liver cells. The ultimate cure for severe cases of amatoxin poisoning is a liver transplant. Due to these therapies, the death rate of cases of Amanita poisoning has been reduced from almost 100 % to 10 to 15 %. Early diagnosis and quick action are the prerequisites for a poisitive outcome.

Mushroom hunters in Europe usually know to distinguish the death cap from edible fungi, so cases among Europeans are rare. Immigrants, however, have more frequently suffered from Amanita poisonings. Many of the victims of the last decade came from Syria, where the death cap is unknown in many regions. In the USA, immigrants from south east Asia are frequent victims of Amanita poisoning. In Australia, signs warn mushroom hunters to abstain from their leisure activity in areas where Amanita phalloides has been introduced.

Does spit contain mRNA? If so, would French kissing a Time Lord cause someone to share all of their memories?

Can a Time Lord read your memories through kissing?

Theoretically, yes—but it's not as simple (or romantic) as it sounds.

🧬 The Biology

Yes, human saliva does contain traces of mRNA. And yes, given the right conditions, Time Lords can interpret human memory RNA, using it to reconstruct emotional impressions or recall sequences from another being's life.

However:

The amount of mRNA present in saliva during casual contact is extremely small.

Memory RNA is not neatly packaged—it's fragmented, degraded, and heavily dependent on the tissues it came from.

Extracting a coherent memory requires focused biological intake, metabolic translation, and neural reassembly—all of which demand time, intent, and cellular integration.

A casual kiss—even of the French variety—is unlikely to transfer enough intact mRNA to reconstruct full memories. At best, a Time Lord might catch tiny emotional echoes:

A flash of a strong emotion

A hazy image

The lingering feeling that you really want cheese

Anything more would require deliberate, targeted biological sampling.

🏫 So...

If Time Lords could casually download your childhood just by snogging you, believe me, Gallifrey would have been much weirder than it already is.

In a recent pre-print study posted to bioRxiv*, a team of researchers investigated the predictive role of gut microbiome composition during acute Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection in the development of Long Coronavirus Disease (Long COVID) (LC) and its association with clinical variables and symptom clusters.

Background LC affects 10–30% of non-hospitalized individuals infected with SARS-CoV-2, leading to significant morbidity, workforce loss, and an economic impact of $3.7 trillion in the United States (U.S.).

Symptoms span cardiovascular, gastrointestinal, cognitive, and neurological issues, resembling myalgic encephalomyelitis and other post-infectious syndromes. Proposed mechanisms include immune dysregulation, neuroinflammation, viral persistence, and coagulation abnormalities, with emerging evidence implicating the gut microbiome in LC pathogenesis.

Current studies focus on hospitalized patients, limiting generalizability to milder cases. Further research is needed to explore microbiome-driven predictors in outpatient populations, enabling targeted diagnostics and therapies for LC’s heterogeneous and complex presentation.

About the study The study was approved by the Mayo Clinic Institutional Review Board and recruited adults aged 18 years or older who underwent SARS-CoV-2 testing at Mayo Clinic locations in Minnesota, Florida, and Arizona from October 2020 to September 2021. Participants were identified through electronic health record (EHR) reviews filtered by SARS-CoV-2 testing schedules.

Eligible individuals were contacted via email, and informed consent was obtained. Of the 1,061 participants initially recruited, 242 were excluded due to incomplete data, failed sequencing, or other issues. The final cohort included 799 participants (380 SARS-CoV-2-positive and 419 SARS-CoV-2-negative), providing 947 stool samples.

Stool samples were collected at two-time points: weeks 0–2 and weeks 3–5 after testing. Samples were shipped in frozen gel packs via overnight courier and stored at −80°C for downstream analyses. Microbial deoxyribonucleic acid (DNA) was extracted using Qiagen kits, and metagenomic sequencing was performed targeting 8 million reads per sample.

Taxonomic profiling was conducted using Kraken2, and functional profiling was performed using the Human Microbiome Project Unified Metabolic Analysis Network (HUMAnN3).

Stool calprotectin levels were measured using enzyme-linked immunosorbent assay (ELISA), and SARS-CoV-2 ribonucleic acid (RNA) was detected using reverse transcription-quantitative polymerase chain reaction (RT-qPCR).

Clinical data, including demographics, comorbidities, medications, and symptom persistence, were extracted from EHRs.

Machine learning models incorporating microbiome and clinical data were utilized to predict LC and to identify symptom clusters, providing valuable insights into the heterogeneity of the condition.

Study results The study analyzed 947 stool samples collected from 799 participants, including 380 SARS-CoV-2-positive individuals and 419 negative controls. Of the SARS-CoV-2-positive group, 80 patients developed LC during a one-year follow-up period.

Participants were categorized into three groups for analysis: LC, non-LC (SARS-CoV-2-positive without LC), and SARS-CoV-2-negative. Baseline characteristics revealed significant differences between these groups. LC participants were predominantly female and had more baseline comorbidities compared to non-LC participants.

The SARS-CoV-2-negative group was older, with higher antibiotic use and vaccination rates. These variables were adjusted for in subsequent analyses.

During acute infection, gut microbiome diversity differed significantly between groups. Alpha diversity was lower in SARS-CoV-2-positive participants (LC and non-LC) than in SARS-CoV-2-negative participants.

Beta diversity analyses revealed distinct microbial compositions among the groups, with LC patients exhibiting unique microbiome profiles during acute infection.

Specific bacterial taxa, including Faecalimonas and Blautia, were enriched in LC patients, while other taxa were predominant in non-LC and negative participants. These findings indicate that gut microbiome composition during acute infection is a potential predictor for LC.

Temporal analysis of gut microbiome changes between the acute and post-acute phases revealed significant individual variability but no cohort-level differences, suggesting that temporal changes do not contribute to LC development.

However, machine learning models demonstrated that microbiome data during acute infection, when combined with clinical variables, predicted LC with high accuracy. Microbial predictors, including species from the Lachnospiraceae family, significantly influenced model performance.

Symptom analysis revealed that LC encompasses heterogeneous clinical presentations. Fatigue was the most prevalent symptom, followed by dyspnea and cough.

Cluster analysis identified four LC subphenotypes based on symptom co-occurrence: gastrointestinal and sensory, musculoskeletal and neuropsychiatric, cardiopulmonary, and fatigue-only.

Each cluster exhibited unique microbial associations, with the gastrointestinal and sensory clusters showing the most pronounced microbial alterations. Notably, taxa such as those from Lachnospiraceae and Erysipelotrichaceae families were significantly enriched in this cluster.

Conclusions To summarize, this study demonstrated that SARS-CoV-2-positive individuals who later developed LC exhibited distinct gut microbiome profiles during acute infection. While prior research has linked the gut microbiome to COVID-19 outcomes, few studies have explored its predictive potential for LC, particularly in outpatient cohorts.

Using machine learning models, including artificial neural networks and logistic regression, this study found that microbiome data alone predicted LC more accurately than clinical variables, such as disease severity, sex, and vaccination status.

Key microbial contributors included species from the Lachnospiraceae family, such as Eubacterium and Agathobacter, and Prevotella spp. These findings highlight the gut microbiome’s potential as a diagnostic tool for identifying LC risk, enabling personalized interventions.
