The monoclonal antibody specifically reacts with major histocompatibility complex (MHC) class I antigens of the mouse and, therefore, it is a valuable tool for studying cytotoxic T-cell interactions with class I positive antigen presenting cells. The primary immunological function of MHC molecules is to bind and present antigenic peptides on the surfaces of cells for recognition by the antigen-specific T cell receptors (TCRs) of lymphocytes. MHC class I molecules are expressed on the surfaces of most cells and are recognized by CD8-positive cytotoxic T-cells, an essential step for initiating the elimination of virally infected cells by T-cell-mediated lysis. MHC class I molecules are heterodimers composed of an alpha (44kD) and a beta (beta microglobulin, 11kD) subunit. The first two structural domains of the alpha subunit associate to form the peptide-binding pocket.
The monoclonal antibody reacts with MHC class I, an antigen that is expressed by all somatic cells at varying levels. Lymphocytes are highly positive, whereas fibroblasts and neurons show only a low level of antigen expression.
