CD69 Antibody, anti-mouse, PE, REAfinity™

01MT08990

Clone REA937 recognizes the mouse CD69 antigen, a type II integral membrane protein with a C-type lectin domain. CD69 is expressed as a homodimer composed of heavily glycosylated subunits. It is rapidly induced upon activation of T and B cells, neutrophils, and NK cells, which is why CD69 has been mostly regarded as an activation marker. The precise role of CD69 in immunity has not been determined because its ligand is unknown. Freshly prepared thymocytes undergoing selection events express CD69, and regulatory roles for CD69 expression in T cell development in the thymus have been suggested.
