HLA Class I B8 Antibody, anti-

Identification and enumeration of HLA class I B8+ cells by flow cytometryClone REA145 recognizes HLA B8, 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 three 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. | Additional information: Clone REA145 displays negligible binding to Fc receptors.
