Technical Support

Our scientists are at the bench daily to produce and validate our antibodies, so they have hands-on experience and knowledge of each antibody’s performance.

About Cell Signaling Technology

Founded by research scientists in 1999, Cell Signaling Technology (CST) is a private, family-owned company headquartered in Danvers, Massachusetts with over 400 employees worldwide. Active in the field of applied systems biology research, particularly as it relates to cancer, CST understands the importance of using antibodies with high levels of specificity and lot-to-lot consistency. It’s why we produce all of our antibodies in house, and perform painstaking validations for multiple applications. And the same CST scientists who produce our antibodies also provide technical support for customers, helping them design experiments, troubleshoot, and achieve reliable results. We do this because that’s what we’d want if we were in the lab. Because, actually, we are.

Our Commitments


In addition to product development and production, CST is also actively engaged in the development of new technologies for signaling analysis as well as mechanistic cell biology research. CST scientists publish their findings in the highest quality peer-reviewed journals including: Nature Biotechnology, Cell, Journal of Immunology, and Journal of Biological Chemistry. Moreover, CST has built and continues to add functionality to our PhosphoSitePlus® bioinformatics resource (www.phosphosite.org), an NIH-funded, publicly accessible knowledge-base containing actively curated information about known and CST-discovered regulatory post-translational modifications on proteins from human, mouse, and related species.
