The CD3 antibody recognizes 22/26/30 kD MW lymphocyte surface molecules associated with the T cell antigen receptor complex. Reacts with 85% of peripheral blood T lymphocytes, 70% of thymocytes, the majority of T cell chronic lymphocytic leukaemias, Sezary leukaemias and approximately 70% of acute lymphoblastic leukaemias of T cell origin.The monoclonal antibody is directed against the CD16- antigen (the Fc gamma receptor III), which is expressed on granulocytes, NK lymphocytes and macrophages. The mobility of the CD16-antigen is dependent on the NA1/NA2 allotype of the neutrophil donor. The monoclonal antibody inhibits the binding of human IgG to the Fc gamma receptor III.The CD56 antigen is a 175-185kDa isoform of the neural cell adhesion molecule (NCAM). It is expressed by lymphocytes mediating non-MHC restricted cytotoxicity and is present on some neural tissues and tumors. It is expressed on natural killer (NK) Cells and a subpopulation of T lymphocytes. NK cells make up approximately 10-25% of peripheral blood lymphocytes.The CD45 antibody recognizes 180, 195, 205, 220, kD MW components of the leucocyte common antigen complex to be found on lymphocytes, monocytes, granulocytes, thymocytes and malignant T and B cells. No reactivity has been observed with primary or metastatic carcinoma cells. Plasma cells or myeloma cells may have weak expression or be negative for this antigen.The CD19 antibody recognizes a 90-95 Kd MW lymphocyte surface antigen identified by monoclonal antibodies belonging to the CD19 cluster. Expressed from the earliest stages of B-progenitor development and on all peripheral B cells including germinal centre B cells, all B cell lines tested and B cell leukaemias tested. The antigen is lost on B cell maturation to plasma cells.
