Anti-HLA Class I Bw6 antibodies, human

Anti-HLA Class I Bw6 antibodies, human

Clone: REA143 | Dilution: 1:11
Clone REA143 recognizes HLA Bw6, a class I human leukocyte antigen (HLA). Expressed on the surface of most nucleated cells, class I molecules are heterodimeric molecules and consist of a type I integral membrane α heavy chain and soluble β2 microglobulin protein. The extracellular region of the heavy chain further consists of 3 domains, of which one comprises the peptide binding groove. Antigens binding to class I molecules are 8–10 amino acids long and play an important role in recognition of the virus infected and malignant cells by cytotoxic T lymphocytes (CTLs). In addition, class I molecules interact with NK cell receptors to modulate the activity of NK cells. Downregulation of HLA class I Bw6 allele has been reported in leukemic patients where it is suggested that via this downregulation, leukemic cells may circumvent attack by CTLs.
Additional information: Clone REA143 displays negligible binding to Fc receptors.
