MHC Class I Antibody [F21-2] (Biotin)

Like their mammalian counterparts, avian MHC Class I molecules, also known as B-F antigens, consist of a highly polymorphic alpha-chain noncovalently bound to the invariant beta2-microglobulin subunit. MHC Class I molecules are expressed on most nucleated cells where they present endogenously synthesized antigenic peptides to CD8+ T lymphocytes, which are usually cytotoxic T cells. The monoclonal antibody F21-2 also reacts with turkey MHC Class I.
