背景资料:Porcine CD8, a type I transmembrane glycoprotein, is expressed as either a CD8alphaalpha homodimer or a CD8alphabeta heterodimer. It is found on most thymocytes and on the suppressor/cytotoxic subpopulation of peripheral T cells. CD8 functions primarily as a co-receptor with MHC Class I-restricted T cell receptors in antigen recognition. The monoclonal antibody 76-2-11 reacts with the CD8 alpha-chain.
