Western blotting, ELISAs, and IHC are all immunoassays, and so all share in common the same basic principle of operation: primary antibodies bind to the target protein of interest, then labelled secondary antibodies bind the primary antibody, allowing for the precise detection of protein.
Western blotting differs from other immunoassays by employing gel electrophoresis and membrane blotting to separate proteins by size before detection, allowing for protein detection as well as molecular weight assessment.Click Here for More
Every immunoassay protocol begins with sample preparation. Western blot, IHC, and ELISA all require different ways of preparing a sample, and nearly every sample type requires specialized treatment in order to produce high-quality, consistent results.
Western blotting requires samples of solubilized proteins to be denatured and charged with SDS in order to achieve size-dependent separation during the SDS-PAGE step.

Nearly every step of the Western blotting procedure comes with a choice. Which sample preparation method is best? How concentrated should the antibodies be? Which blocking buffer will work best?
The Boster Bio optimization tips are meant to help answer those questions and more. Take a look at our optimization guides to help inform your decisions, optimize your experiments, and get better results.Click Here for More
Every researcher eventually encounters trouble with an experiment. Blots appear blank, or IHC stains come out blurry, or ELISA standard curves come out wonky, or any of a thousand different problems.
Proper controls can help eliminate a great number of possible sources of error, but many troubles will remain. Check out the Boster troubleshooting guides for the most common troubles, their sources, and how to resolve them.Click Here for More
