Nature Methods , 13, pp DOI: Combining several validation strategies is the most effective way to demonstrate antibody specificity and validate performance.
How to Validate Western Blot Antibodies
Blocking buffers enhance the sensitivity and specificity of Western blotting by reducing non-specific binding of antibodies to the membrane surface and to off-target sample proteins. Your goal is to block these non-specific sites without affecting detection of the target protein. But each antibody-antigen pair is unique — and the blocking buffer you choose can have a surprisingly strong influence on antibody specificity and performance.
Kothari M. Meth Mol Biol , , pp Cross-reactivity of your secondary antibodies can also influence the outcome of your Western blot experiments. Careful selection of primary and secondary antibodies is critical to prevent cross-reactivity on multiplex NIR fluorescent Westerns. Qualitative or Quantitative Westerns?
Transfer Options Wet tank vs. How to Validate Antibodies Antibody validation is an important part of Western blot analysis. Read the previous article Compare Proteins Accurately. Primary Antibodies: Specificity and Selectivity In your experimental context, the primary antibody must recognize its intended target with minimal binding to other proteins in the sample.
Affinity is the strength of the bond between the antibody and each epitope of an antigen. Primary Antibody.

Tips for two-color fluorescent Westerns If your target proteins have similar molecular weight, choose primary antibodies raised in two different host species , so they can be discriminated by the secondary antibodies. When I stumbled across this kind of literature that romances this, written when these wide open spaces were still so much more wider, it was exciting.
She has found the stories to be alive with descriptive adjectives, but almost completely lacking in adverbs, which would only serve to slow the galloping pace of the writing. The books were always intended to provide an escape for the reader, and the moments of escape are very deliberately constructed to provide that experience. Her computer science skills have played a role as well.
Dan Jurafsky, an expert in computational linguistics, has been elected a fellow of the American Association for the Advancement of Science. A periodic review of the artificial intelligence industry revealed the potential pitfalls of outsourcing our problems for technology to solve rather than addressing the causes, and of allowing outdated predictive modeling to go unchecked.
