SM024LE recognises a non polymorphic epitope on the mouse CD8 alpha chain. Antibodies produced by clone YTS105.18 have been reported to block MHC I dependent T-cell responses in vitro and in vivo, and induce transplantation tolerance in combination with CD4 antibodies.

CD8 T cell surface antigen is heterodimer of an alpha and a beta chain linked by two disulfide bonds. It belongs type I membrane protein. Selectively expressing of CD8 on a subset of T cells leads to CD8 T cell development. Through identifying cytotoxic/suppressor T-cells that interact with MHC class I bearing targets, CD8 is thought to play a role in the process of T-cell mediated killing. Veillette et al (1988) found the CD8 is associated with the internal membrane tyrosine-protein kinase p56lck.Synonyms: CD8 alpha chain, CD8A, MAL, T-cell surface glycoprotein CD8 alpha chain, T-lymphocyte differentiation antigen T8/Leu-2
