Clone REA672 recognizes the class I human leukocyte antigens (HLA) B and C. 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, one of which 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 REA672 displays negligible binding to Fc receptors.
