Product Overview
Clone 22I71 is a rabbit monoclonal antibody that recognizes interleukin-7 receptor subunit alpha (gene IL7R) in human, mouse and rat samples and is validated for Western blot, IHC and flow cytometry. The predicted molecular weight is 51.6 kDa, and the supplier reports an observed band at about 75 kDa.
IL-7 receptor alpha (CD127) binds IL-7 together with the common gamma chain and also forms the receptor for TSLP with CRLF2. It is essential for T-cell development and for the survival of naive and memory T cells. Low CD127 expression is commonly used to help identify regulatory T cells by flow cytometry.
