Have you seen some of the new HDR stuff on KDE plasma 6? Still early days, but very exciting!

https://zamundaaa.github.io/wayland/2023/12/18/update-on-hdr-and-colormanagement-in-plasma.html

oh that is interesting! sounds very promising.

“SDR Color Intensity” is inspired by the color slider on the Steam Deck. For sRGB applications it scales the color gamut up to (at 100%) rec.2020, or more simply put, it makes the colors of non-HDR apps more intense, to counteract the bad gamut mapping many HDR displays do and make colors of SDR apps look more like when HDR is disabled

I guess this goes some way to answering why colour accuracy for SDR content was so dodge when I turned on HDR on windows (which lacks such a slider, just a brightness slider). "the bad gamut mapping many HDR displays do" is big oof but also explains a lot. the mathematics for colour space transformation is pretty well-defined, so if hardware is implementing them incorrectly, that's really frustrating. older screens are working with standards that predate the idea of colour management, but now we're bringing in all these new display signalling standards (PQ and all that), it seems like a golden opportunity to do things properly this time... so of course we don't lmao.

the colorimeter I got has an option for high brightness/HDR screens, but I haven't really tested it yet. 'measure your screen colorimetrically and compensate in software' works decently well in SDR land, but I'm not sure what happens in HDR. I haven't played any HDR-enabled games since I got this colour accuracy bug, so I haven't had cause to try and figure out the ins and outs of it yet.

it seems like KDE intend to be a lot less black-box about it than Microsoft, which is very welcome.

ive had "guy who has had an unrealistic number of different jobs" in my bio for ages but just now i was reminded about when i interned in an immunology lab and was joking about how, look yes im primarily a programmer but things like that (the bio lab background) and that i've worked on Arduino stuff/actual electronics at least a little bit, even though i was a software guy on that project and not a hardware guy (this was in the shark tagging lab), this is all because being solely a programmer is not enough to actually satisfy my obsession w cybernetic brain implants (for straightforwardly villainous purposes).

you also have to be a neuroscientist and an biomedical engineer. ye i am a programmer because it's the easiest to do without additional formal education but the other stuff i just have to run around collecting relevant experience from the various gigs i've had. so it's cool i've spent time in a biology lab and done PCR and colorimetric assays and gel electrophoresis and that gives me a BIT of useful knowledge for certain stuff, but i really do need to get more neuroscience background. or need to find someone who does and doesn't ask a lot of questions.

I’ve struggled with iron deficiency anemia for years and tend to bruise very easily. I always find random bruises on my skin and since I’m very strange and love documenting everything, have kept a journal for years estimating the ages and healing progression of all my bruises, cuts, and burns. My favorite pastime is lining up my bruises with tables or couch edges to see where and how I managed to get them…

Our town coroner even gave me this colorimetric scale for assessing bruising (it’s like an L shaped plastic ruler; small towns amirite?) and I use it as a bookmark!

Point of the story, is I can only imagine what fun I’d have finding bruises and love bites all over my body the day after a rather rough sex session. Ideally I’d need help counting them all. We’d celebrate them healing by making more in new, creative places and make a game out of trying to control their shapes and sizes before they develop. I want a heart bruise on my thigh!

Too niche?

Liquid Handling Solutions for ELISA and Other Immunoassays

Enzyme-linked immunosorbent assays (ELISA) and other immunoassays are essential tools in laboratories for detecting and quantifying biological molecules such as proteins, antibodies, and hormones. These assays are widely used in diagnostics, research, and pharmaceutical industries due to their sensitivity and specificity. However, for these tests to deliver accurate and reproducible results, precise liquid handling is crucial.

In this blog, we’ll explore how liquid handling instruments play a key role in ELISA and other immunoassays, and what tools can enhance the efficiency and accuracy of these assays. 

Understanding the Role of Liquid Handling in ELISA and Immunoassays

ELISA and immunoassays typically involve multiple steps, such as adding reagents, washing, and detecting signals from the sample. Each of these steps requires precise dispensing of liquids to ensure proper binding and reaction between molecules. Even small inconsistencies in pipetting can lead to errors in results, compromising the reliability of the data. 

Here are some steps where precise liquid handling is vital:

Sample Dispensing: Accurate measurement of the sample to ensure consistent concentration across wells. 

Reagent Addition: Reagents, such as antibodies or substrates, must be added uniformly for reproducibility. 

Washing: Thorough washing of wells to remove unbound material and minimize background noise. 

Substrate Addition: Ensuring equal amounts of substrate to each well for uniform colorimetric or fluorescent signals. 

Liquid Handling Solutions for ELISA and Immunoassays

Let’s take a look at some advanced liquid handling solutions that help labs achieve high-quality ELISA and immunoassay results. 

1. Micropipettes

Micropipettes are essential tools for handling small volumes of liquid in immunoassays. Both manual and automated micropipettes are widely used for dispensing reagents and samples in ELISA. Key factors when selecting micropipettes for immunoassays include accuracy, precision, and ergonomic design.

Microlit NERO Micropipettes: Known for its ergonomic design and superior accuracy, the NERO range includes both single-channel and multi-channel micropipettes. Multi-channel options are particularly useful in ELISA, allowing multiple wells to be filled simultaneously, speeding up the process and reducing variability. 

2. Electronic Dispensers

Electronic dispensers simplify repetitive pipetting tasks and reduce the chances of human error. They are useful for adding reagents in fixed or variable volumes during different stages of ELISA and immunoassays. 

Microlit E-BURETTE: This E-Burette is designed to dispense precise amounts of reagents effortlessly. It eliminates user fatigue and enhances consistency, which is critical when handling large numbers of samples in immunoassays.

3. Bottle Top Dispensers

For laboratories dealing with multiple reagents in large volumes, bottle top dispensers provide an efficient solution. These dispensers allow easy, accurate, and contamination-free transfer of reagents directly from the bottle.

Microlit BEATUS: A bottle top dispenser with excellent chemical compatibility and precision, BEATUS ensures that reagents are safely and accurately dispensed, reducing the risk of cross-contamination in ELISA and immunoassays.

4. Automated Liquid Handling Systems

Automation is transforming laboratories by increasing throughput and minimizing manual intervention. Automated liquid handling systems can perform complex pipetting tasks, including sample preparation, washing, and reagent addition, with precision and speed.

While high-throughput labs benefit greatly from automation, smaller labs can still achieve consistency by using electronic pipettes and semi-automated dispensers for immunoassays.

Best Practices for Liquid Handling in ELISA and Immunoassays

To make the most of liquid handling solutions and improve the accuracy of immunoassays, labs can follow these best practices:

Regular Calibration: Ensure that pipettes and dispensers are regularly calibrated to maintain accuracy.

Use Multi-Channel Pipettes: Multi-channel pipettes can significantly reduce variability between wells, particularly when adding samples or reagents in ELISA plates.

Minimize Air Bubbles: When aspirating and dispensing, be mindful of air bubbles as they can cause inconsistencies in volume and affect results.

Avoid Touching the Sidewalls: During pipetting, avoid touching the sides of wells as this can lead to inaccurate volumes and cross-contamination. 

Conclusion

Liquid handling plays a fundamental role in ensuring the success of ELISA and other immunoassays. By using precise and reliable tools like micropipettes, electronic dispensers, and bottle top dispensers, labs can improve the accuracy and reproducibility of their assays.

Microlit’s range of liquid handling instruments is designed to meet the high demands of immunoassays, ensuring that labs can carry out their research and diagnostics with confidence. Whether you’re running routine tests or handling critical samples, investing in high-quality liquid handling solutions will enhance the reliability of your results and streamline your workflows.

Nanomaterials, Vol. 14, Pages 1364: Development of a Gold Nanoparticle-Based Sensor for Authentication of Organic Milk Based on Differential Levels of #miRNA

Dairy production systems significantly impact environmental sustainability, animal welfare, and human health. Intensive farming maximizes output through high-input practices, raising concerns about environmental degradation, animal welfare, and health risks from antibiotic residues. Conversely, organic farming emphasizes sustainable practices, animal welfare, and minimal synthetic inputs, potentially enhancing biodiversity, soil health, and milk quality. Micro#RNAs (#miRNAs), non-coding #RNAs regulating gene expression, are promising biomarkers due to their response to various conditions. In this study, #miRNAs bta-miR-103 and bta-miR-155, which are abundant in milk from pasture-fed cows, were selected. Additionally, bta-miR-215, which is abundant in milk fat from intensive systems, was also studied, in order to differentiate dairy production systems. A novel, cost-effective gold nanoparticle (AuNP)-based sensor was developed for #miRNA detection, leveraging the unique plasmonic properties of AuNPs for visual detection. The method involves functionalizing AuNPs with complementary #RNA probes and detecting #miRNA-induced aggregation through colorimetric changes. This rapid, results in 30 min, and sensitive, visual limit of detection of 200 nM, assay requires minimal instrumentation and can be easily interpreted, offering significant advantages for field implementation in characterizing dairy production systems. This study demonstrates the successful application of this sensor in detecting #miRNAs in 350 nM #miRNA spiked raw milk, highlighting its potential for in situ dairy industry applications. https://www.mdpi.com/2079-4991/14/16/1364?utm_source=dlvr.it&utm_medium=tumblr
