Bio-Rad’s Western Blotting University is a five-part，on-demand webinar series that walks you through the basics of all the steps of the western blotting process.Watch all five to get a certificate and become a western blotting master。

Casting your own polyacrylamide gel is tedious and can lead to inconsistencies from experiment to experiment.Precast gels offer high quality resolution and lot-to-lot consistency in addition to the time savings。

可Seal available precast gels。

Come to our Western Blot Learning Center to get protocols and to learn everything there is to know about polyacrylamide gels and protein gel electrophoresis。

Ion depletion is a common problem that can be caused by running buffer inconsistencies.A great way to minimize this would be to incorporate premade10xrunning buffer into your experimental workflow.This ensures that you always have freshly made1x stock when running gels。

Signal saturation a blot limits the dynamic range，which leads to loss of data.It is important to minimize signal saturation when imaging the blot in order to yield accurate results。It is also crucial to perform normalization to account for pipetting error，further confirming the accuracy of your sults。

Knowing the total concentration of your protein sample prior to gel electrophoresis important to prevent overloading of sample in the gel.Always determine protein concentration after sample preparation to ensure you are within optimal working range.A Bradford protein assay is an easy to determine protein concentration。

Minimizing background on your western blot can enhance your results significantly.In order to achieve an accurate and quantifiable blot，the background should be uniform and minimal across the entire blot.There are multiple factors to consider when attempting to reduce blot background。

Optimizing the blocking step prior to immunodetection is an essential part of western blotting.A good block can greatly enhance your results while a bad block can potentially mask critical experimental findings.If selecting the right blocking buffer proves to be a challenge， then using a universal blocking buffer like EveryBlot Blocking Buffer may be the solution。
