Mouse anti Human CD56

Catalogue number: 561

Product Type Monoclonal Antibody
Units250 µg
Species reactivity Human
Application Flow Cytometry
Immunohistochemistry (paraffin)

CD56, M.W. 150,000, is expressed on approximately 10-25% of human peripheral blood lymphocytes. CD56 (NKH-1) is expressed on human peripheral blood natural killer cells, representing a pan NK-cell antigen. Expressed on non-MHC-restricted cytotoxic T cells. ExalphaÕs CD56, clone C5.9 has been recognized as the superior CD56 antibody for Flow Cytometry applications because of itÕs specific and intense staining. In fact, our CD56 is bright enough to be used in FITC! Now this antibody is proven to work in formalin fixed paraffin embedded section. Available concentrated, pre-diluted in dropper bottles, or conjugated to several flurochromes for manual use or automated applications.

Synonyms: CD56, NCAM, Neural Cell Adhesion Molecule


Immunogen: CD56=Derived from the hybridization of mouse Sp2/0 myeloma cells with spleen cells from BALB/c F1 mice immunized with KG1a cell line.
