#PVDF Transfer Membranes

[praxilabsvirtualsimulations]

The blog "The Concept, Processes, and Applications of Western Blotting" published on PraxiLabs outlines the Western blot (or protein immunoblot) technique, highlighting its indispensability in modern biomedical research and various laboratories. This analytical method, rooted in molecular biology and immunogenetics, employs antibodies to specifically detect antigens, allowing for the identification of a particular protein within a sample alongside information on protein size and abundance.

Originating from the collaborative work of Harry Towbin, Julian Gordon, and Theo Staehelin in 1979, the development of protein blotting techniques marked a significant advancement in the field. Their pioneering work facilitated the electrophoretic transfer of proteins from polyacrylamide gels to nitrocellulose sheets, thereby setting a foundational technique for numerous scientific investigations.

Western blotting operates on the principle of separating proteins within a sample based on molecular weight through gel electrophoresis. These proteins are then transferred (blotted) onto a more durable surface, such as a nitrocellulose or PVDF membrane. The detection of the protein of interest is facilitated by the use of specific antibodies.

Let’s explore the Western Blot method step-by-step.

Sample preparation: Involves preparing and loading the sample onto a gel for electrophoresis.

Electrophoretic separation: Proteins are separated by size using gel electrophoresis.

Protein transfer: The separated proteins are transferred from the gel to a membrane.

Blocking: Nonspecific binding sites on the membrane are blocked.

Antibody probing: The membrane is incubated with primary and secondary antibodies to detect the protein of interest.

Detection: Various methods, including chemiluminescence and fluorescence, are used to visualize the protein-antibody complexes.

Imaging and analysis: The final steps involve capturing images of the membrane and analyzing the detected signals to estimate protein size and quantity.

The article highlights the benefits and applications of Western Blotting.

One of the key advantages of Western Blotting lies in its sensitivity and specificity, making it highly effective in analyzing complex protein structures. This is crucial not only in research for obtaining molecular insights but also in clinical settings for making accurate diagnoses.

Sensitivity: demonstrates the ability to identify minuscule protein quantities within samples, as slight as 0.1 nanograms, which is an invaluable tool for early diagnostics in detecting minimal immune reactions triggered by viruses or bacteria in patient samples.

Specificity: originates from two principal factors attributing to the western blot technique. Firstly, the application of gel electrophoresis allows the classification of proteins based on their size, charge, and structure. This initial sorting is instrumental in the identification process, as the resulting patterns on the gel can provide preliminary insights regarding the protein or peptide of interest.

What about the applications of Western Blotting?!

The Western blot technique has a wide range of uses in scientific and clinical approaches, such as:

Biological sciences: It enables researchers to ascertain the presence, size, and amount of protein expression related to various tissues or cell types. This technique is pivotal for understanding protein expression levels, monitoring protein purification processes, and studying the effects of diseases or treatments on protein behavior. Its application extends to comparing protein expressions across different tissues or observing how proteins respond to specific treatments or diseases.

Medical diagnosis: Western blotting has found significant applications in the medical diagnostic field, especially as a confirmatory test for various diseases. For instance, it is widely used in the diagnosis of HIV, where it confirms the presence of HIV antibodies in blood samples following a preliminary ELISA test. In addition, Western blotting assists in diagnosing other conditions, such as Lyme disease, by detecting antibodies against specific pathogens, offering a layer of confirmation that enhances the accuracy of initial screening tests.

METHODS FOR PURIFYING AND ANALYSING PROTEINS VIA WESTERN BLOTTING

For many years, western blotting was a primary method in molecular biology and techniques such as proteomics (the large-scale study of proteomes: a set of proteins produced in an organism, system, or biological context). Given that western blot is a multistep process that frequently necessitates specialised interpretation, potential errors and variations at any step can jeopardise the reliability and reproducibility of its results.

Given this situation, many advanced and sophisticated approaches to improving the western blot protocol have been developed over the last two decades. These enhancements are more automated and sensitive, with high potential for reducing potential issues with the traditional western blot method. Western blotting's improved sensitivity and innovative equipment advancements have the potential to broaden the field of clinical applications for this fundamental method.

Helvetica Health Care explains the western blot technique as a method of purifying and analysing proteins, as well as new developments in western blotting methodology, in this article.

WHAT EXACTLY IS THE WESTERN BLOT TECHNIQUE?

Traditionally, the western blotting method involves seven steps, as below.

Sample preparation from cells or tissue lysates

Separation of proteins by gel electrophoresis

Protein transfer in a nitrocellulose or polyvinylidene fluoride (PVDF) membrane,

Blocking of non-specific proteins on membrane

Primary Antibody incubation

Secondary Antibody incubation

Protein detection & analysis

WHAT ARE THE NEW DEVELOPMENTS IN THE WESTERN BLOT DOMAIN AND WHAT CHARACTERISTICS DO THEY HAVE?

Below are some innovations that have enhanced the western blot protocol and addressed the potential problems in its application in protein purification and analysis.

CAPILLARY AND MICROCHIP ELECTROPHORESIS (MCE)

MCE has higher sensitivity and resolution than traditional techniques, allowing for the detection of multiple target proteins from a single cell lysate sample. The method not only allows for parallel multiplexed tests of a set of proteins using a small sample amount, but it also eliminates blocking stages and has faster analysis times (8 min for electrophoretic resolution). MCE, while still in development, has the potential to be significantly improved with additional work.

AUTOMATED MICROFLUIDIC PROTEIN IMMUNOBLOTTING

Automated protein immunoblotting is a programmable and controllable technology that combines PAGE (polyacrylamide gel electrophoresis) and blotting in a single device. It saves time, avoids multiple test stages, and reduces the amount of equipment and reagents required. Because it can detect free prostate-specific antigens in a sample of human seminal fluid in less than 5 minutes, this technology is both cost-effective and reagent-efficient. The method is constantly being improved to improve sensitivity and enable protein quantification.

SINGLE CELL-RESOLUTION WESTERN BLOTTING

This sensitive method has also been used to investigate protein variations in stem cell signalling and differentiation. It can detect specific cell-to-cell changes in protein expression. MiloTM (ProteinSimple), the world's first Single-Cell Western platform, can measure protein expression (up to 4 proteins per cell simultaneously) in 1000 single cells in about 4 hours.

DIGIWEST

DigiWest, a simplified version of the standard procedure, improves western blotting throughput by requiring less lysate, target detection, and antibody. However, this method requires biotinylation of the target proteins, requires specialised reagents and equipment, incurs initial startup costs, has issues with translating the digital DigiWest results to western blot mimics, and has specifics about some procedures, such as the complex and difficult elution of proteins from PVDF membranes.

SIMPLE WESTERN

Simple Western is a method developed by ProteinSimple (San Jose, California) that is based on CE-SDS (Capillary electrophoresis sodium dodecyl sulphate), in which separated proteins are linked to the capillary wall by a patented photo- (ultraviolet) induced chemical crosslink. The method can use up to 90 different antibodies at the same time, is relatively quick, and requires small amounts of sample. It can also perform standard curve quantification, similar to high-pressure liquid chromatography (HPLC), and improve reproducibility. However, it necessitates the use of specialised reagents.

MICRO-LOADER

The Micro-loader technology has improved the sensitivity of the western blot assay and PAGE. To load samples, it employs a sample micro-loader device with a funnel-like design. This technique is highly effective for measuring protein expression and phosphorylation in samples that are few, difficult to find, and limited in quantity because it only requires a small number of loading samples for signal detection.

THIN-FILM DIRECT COATING WITH SUCTION-WESTERN BLOTTING (TDCS)

Western blotting has significant limitations due to high antibody consumption and lengthy operating times. TDCS, a capillary-tube-based technique, aims to reduce antibody and time consumption in western blotting. This quick and sensitive detection method allows for the quantitative study of multiple antigen-antibody interactions, as well as multiple protein interactions.

BLOTTING OF DIFFUSION

SDS-PAGE Single-prefabricated gels on plastic support are a quick and easy way to make multiple blots using diffusion blotting. Diffusion blotting allows for the comparison of several proteins on blots from the same gel. Protein transmission rates by diffusion blotting are 10% in 3 minutes, 20% in 20 minutes, and 40% to 60% in 3 hours. When compared to electroblotting, the technique may increase the amount of proteins efficiently delivered to the membrane surface. As a result, when quantitative protein exchange is not required, diffusion blotting is the preferred method.

MICRO WESTERN

Soon, micro western will be a proper western blot technique for confirming the diagnosis of purified HIV p24 and gp120 proteins in blood plasma. The Micro-Western may be vital for detecting infectious diseases and cancer, despite not being widely available.

SYSTEM OF IBIND WESTERN

Thermo Fisher Scientific's iBind Western procedure makes use of a low-cost semi-automated western blotting structure that uses sequential flow technology to distribute chemicals and antibodies to different compartments. Cleaner western blots will result from using the iBind Western Systems and highly specialised primary and secondary antibodies.

BLOT CYCLER

Every step of membrane processing is automated with the BlotCycler (Precision Biosystems, USA), and up to 12 membranes can be processed at once. The BlotCyclerTM is an Automated Western Blot Development system that improves repeatability and sensitivity by completing all blot cleaning, trapping, and incubation steps. It is also simple to programme all of the actions for specific operations.

SYSTEM OF SNAP I.D.

In a low-cost system of SNAP i.d. 2.0, solvents are uniformly distributed via the tissue using a technique based on a vacuum and a flow distribution system (Merck, USA). Its main advantage is that washing, antibody incubation, and blocking all take about 30 minutes. The SNAP i.d.® 2.0 gadget actively forces reagents through the membrane, unlike conventional Western blotting, which depends on diffusion to transfer reagents.

Washes, antibody recollection, and antibody-antigen binding have been improved. The SNAP i.d.® 2.0 delivers new, cutting-edge western blotting characteristics with an immunodetection capability in 30 minutes without using additional reagents (e.g., antigen, antibody, or detection reagents).

RETENTION IMPROVEMENT OF HORMONES OF THE PEPTIDE ON THE MEMBRANE OF BLOTTING

Western blotting is significantly improved by treating the PVDF membrane used in this method with glutaraldehyde (0.2%) for fifteen minutes in a saline solution containing tween-80. In western blotting, the addition of glutaraldehyde to the membrane prevented or reduced the quantity of insulin loss.

Apart from these, two more techniques that have improved the conventional method are

Analysis of western blot utilising molecular weight marker detecting secondary antibody

Total and target protein co-detection by immunoblotting of fluorescent ECL and labelling of Cydye

Many innovations in western blotting techniques to transfer proteins from gel to membrane have also been observed, such as vacuum blotting, centrifuge blotting, multiple tissue blotting, and so on. The Trans-Blot Turbo, the iBlot® dry blotting system, and the PierceTM Power Blot Cassette are all improvements in protein transfer methods from gels to membranes. The transfer time is reduced from an hour or overnight to at most 10 minutes when these new techniques are used.

HHC offers the ZeptoMetrix WESTERN BLOT for in vitro detection of antibodies to SIV in serum or plasma and is available in 10 or 30-strip kit formats.

Western Blot

A western blot can detect specific protein molecules from a mixture of proteins.  They can also be used to evaluate the size of a protein of interest, and to measure the amount of protein expression. 

Gel electrophoresis

The proteins of the sample are separated by isoelectric point (pI), molecular weight, electric charge, or a combination of these factors. 

Samples are often boiled first to denature the proteins -  prevents proteases (enzymes that break down proteins) from degrading samples.

Most commonly, this uses polyacrylamide gels and buffers loaded with sodium dodecyl sulfate (SDS). SDS-PAGE (SDS polyacrylamide gel electrophoresis).

Proteins are covered in the negatively charged SDS - becoming anionic - and migrate towards the positively charged (higher voltage) anode through the acrylamide mesh of the gel. 

Smaller proteins migrate faster through this mesh, and the proteins are thus separated according to size.

The different rates of advancement (different electrophoretic mobilities) separate into bands within each lane. 

The concentration of acrylamide determines the resolution of the gel.

One lane is a marker/ladder - a mixture of proteins of known molecular weights, to act as a control and compare results to so as to estimate the sample’s molecular weight.

Transfer

To make the proteins accessible to antibody detection, they are moved onto a membrane made of nitrocellulose or polyvinylidene difluoride (PVDF). 

Electroblotting uses an electric current to pull the negatively charged proteins from within the gel onto the membrane while maintaining the organization they had within the gel. 

Blocking

Blocking of non-specific binding prevents interactions between the membrane and the antibody used for detection of the target protein. 

Membrane is placed in a dilute solution of protein – typically 3–5% bovine serum albumin (BSA) or non-fat dry milk in tris-buffered saline (TBS) or I-Block, with a minute percentage (0.1%) of detergent 

The protein in the dilute solution attaches to the membrane in all places where the target proteins have not attached. 

When the antibody is added, it cannot bind to the membrane, and therefore the only available binding site is the specific target protein. 

This reduces background - clearer results, and eliminates false positives.

Primary antibody

A solution of primary antibody (diluted in either PBS or TBST wash buffer) is incubated with the membrane under gentle agitation. 

This binds to the target protein.

The membrane is washed several times in wash buffer to remove unbound primary antibody,

Secondary antibody

Membrane is exposed to another antibody 

Which recognises and binds to the species-specific portion of the primary antibody (eg anti-mouse secondary antibody will bind to almost any mouse-sourced primary antibody).

Secondary antibody is commonly linked to biotin or a reporter enzyme 

Several secondary antibodies will bind to one primary antibody and enhance the signal.

Western blot binding

As with most immuno tests, an enzyme can be attached to the secondary antibody that will produce a coloured reaction product - visible on the membrane so that the test can be read. 

Another method uses a near-infrared (NIR) fluorophore-linked antibody - light produced from the excitation of a fluorescent dye is static, making fluorescent detection more precise and accurate 

A radioactive label could also be coupled to the secondary antibody.

Hello! I love your blog! I had a question about Western blots since I noticed you do a billion of them. Do you have any tips on getting a good band? I don't know if possibly it's just the antibody I am using or if I am doing something mechanistically wrong. Those westerns can be so tricky at times!! Thanks:)

hi!! and i love YOUR blog! (i follow via my personal, jncera, btw). also btw, my lab mate is a phd candidate in nutritional sciences too!

aahhh westerns. i do too much westerns probably. and just to give you a brief background of what protocol i use, my lab buys our gels from Bio-Rad, and we use PVDF membrane and a chemiluminescence detection method. we also use commercial antibodies (cell signaling is our go-to), and most of our protein comes from whole cell lysate. 

My tips are more-so “here are some variables you can optimize” because every protocol can vary slightly depending on your antibody, protein lysate, gel, blot, detection method, etc etc. Also, unless I know your exact protocol and see your exact band image, I can only speculate as to what may be going wrong. 

If you make your own SDS-PAGE gels, consider buying them. I’ve made my own gels before, and I know it can be a tricky process at times. If you think that’s a questionable variable, you can go commercial. Because all of our equipment is from BioRad, we use their precast gels. We also buy commercially made Running buffer, Transfer buffer, and TBS (for washes). Less variability that way, and since they come as 10x and we use 1x, it’s really not that expensive. 

Optimize the amount of protein you load/well. I’ve found that my best results are between 8 and 20 ug/well. Too little protein and you won’t have a bright signal; too much protein and you may oversaturate the signal. Our lab recently made the switch from 10-well gel (using up to 30 ug of protein/well) to 15-well gels (uses up to 12 ug protein/well) and the 15-well blots are soooooo much more beautiful! So I think it has something to do with loading less protein (which is, i know.. slightly counterintuitive).

Play around with different blocking buffers. For example, milk has phosphorylated proteins, which may be non-specifically detected by antibodies to phosphorylated proteins. You can research online for different blocking buffers. 

Likewise, try different commercial antibodies. Not every antibody is created equal. In general, monoclonal antibodies are more specific than polyclonal, but there are so many variations between companies (which is unfortunate and is the root of many reproducibility issues). Speaking of reproducibility, it’s also good practice when using commercial reagents to test from different companies. That way you can be sure your result is actually real, and not a result of some fluke by one company or another. Some companies may even offer you free samples if you call them, or will include a sample of a positive control lysate. One World Lab specializes in selling antibody samples from many antibody providers at reasonable prices if you’d like a bunch to test. We use them and they’ve been pretty helpful. 

Related to antibodies, use different dilutions. Just because the protocol the company gives you says “use 1:1000″, doesn’t mean it’ll work for your protein of interest. Always do a serial dilution (or at least try one high and one low dilution) whenever testing a new antibody or a new sample. 

Ensure a good transfer first before moving on. We use Ponceau S solution to stain our blots immediately after transfer to ensure that our bands are there, and there aren’t any bubbles in areas of interest. Saves us time (so we’re not waiting until we finally image the blot to find out if the transfer worked), and when we do image the blot and nothing shows us, at least we know it’s not the protein transfer step at fault. (Brief protocol: wash blot with your washing buffer, add Ponceau S at RT rocking, wait 1-2 min, can save Ponceau for reuse, add ddH2O to stained blot to better visualize bands, continue washing blot until blot is no longer pink, proceed with your normal protocol)

If your band is too light, but the ladder is showing up fine, consider blocking the ladder when imaging. Like with a piece of paper or thick cardboard. The imaging machine we use automatically adjusts the image and sometimes this causes our bands to be under-developed because the ladder is just too darn bright. So I take one image of the blot with the ladder, and then another image where I put a piece of cardboard over the ladder, and voila! My band shows up! (And then I note that next time I run this sample/antibody, I either increase the concentration of my primary or secondary antibody, or just load less ladder). 

Optimize your detection. When I started we had a lot of issues with our detection kit (we use ECL). Finally we tried some ThermoFisher SuperSignal West Femto and it worked beautifully. 

That’s all I can think of right now! And remember: everything takes practice. You could be following the directions perfectly, but there are sometimes just small technical things that are hard to notice but get perfected over time. Just keep at it!

You can also look up Western blot troubleshooting guides/advice from companies like ThermoFisher, forums like ResearchGate, or just googling around. Good luck!
