68 kDa (Nakuchi, 1997)

CD8 is a 68 kDa disulphide-linked, transmembrane glycoprotein. The CD8 molecule serves as a receptor for MHC class I molecules and can mediate a function as a coreceptor in TCR-ligand binding and T-cell activation. Its cytoplasmic part is associated with the p56Ick tyrosine kinase (Nakuchi, 1997). CD8 is expressed by the great majority of cortical thymocytes and approximately 30% of medullary thymocytes, and by class I major histocompatibility complex restricted, mature suppressor/cytotoxic T cells. In addition a proportion of gamma delta T cells and NK cells express CD8 (Nakuchi, 1997). Thus, CD8 is expressed by about 25-35% of peripheral T cells, and about 30% of NK cells express low levels of CD8 (Leong, 1999). The specificity of Anti-CD8, DK25, is equivalent to that of the CD8-clustered antibodies OKT8 and Leu-2a (Stein, 1984).
