CD20 / MS4A1 (B-Cell Marker); Clone L26 & IGEL/773 (Concentrate)
Immunogen: Human tonsil B-cells (L26); Recombinant human MS4A1 protein (IGEL/773)
Clone: L26 & IGEL/773
Isotype: IgG2a, kappa (L26); IgG2a, kappa (IGEL/773)
Species Reactivity: Human. Others not known.
Positive Control: Daudi, Raji, and U266, and human lymphocytes, lymph nodes and tonsils.
Specificity: Recognizes a protein of 30-33kDa, which is identified as CD20. Its epitope is located in the cytoplasmic domain of CD20 and was, therefore, ascribed as CD20cy in the 5th Workshop.
