特異性:Porcine CD8a, Mr 32-34 kDa Porcine CD8, a type I transmembrane glycoprotein, is expressed as either a CD8 alpha alpha homodimer or a CD8 alpha beta 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. MAb 76-2-11 reacts with the CD8 alpha chain.1-3
