Mouse anti Human CD23 antibody, clone 1B12 recognizes the human CD23 cell surface antigen also known as FcƐRII (Fc epsilon Receptor II). CD23 is a 45 kDa glycoprotein that functions as a low affinity receptor for IgE.

CD23 is expressed by peripheral B lymphocytes, cells of B cell chronic lymphocytic leukaemia and upon EBV transformed lymphoblastoid cells.
