Product Overview
Clone 19R00 is a rabbit monoclonal antibody that recognizes ribosomal protein S6 kinase beta-2 (gene RPS6KB2) in human, mouse and rat samples and is validated for Western blot, IHC, ICC/IF and flow cytometry. The predicted molecular weight is 53.5 kDa, and the supplier reports an observed band at about 53 kDa.
S6K2 (RPS6KB2) is a p70 ribosomal S6 kinase closely related to S6K1. It is activated downstream of mTOR signaling and phosphorylates ribosomal protein S6, contributing to growth-factor and nutrient control of cell growth, and it is more concentrated in the nucleus than S6K1.
