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. ItÍs 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 thatÍs what we'd want if we were in the lab. Because, actually, we are.
