Mouse anti Human CD8 monoclonal antibody, clone RPA-T8 recognizes the alpha-chain of the human CD8 antigen, a ~32 kDa single pass type 1 membrane glycoprotein containing a single Ig-like V-type domain. CD8α forms either homodimers or disulphide bond linked heterodimers with the CD8β chain. CD8 is expressed by thymocytes, the cytotoxic-suppressor subset of T cells and weakly by NK cells. CD8 functions as a receptor for MHC Class I molecules.
