Product Details anti-CD20 Antibody

Binding Specificity: AA 213-297

Purpose: CD20 / MS4A1 (B-Cell Marker) Antibody

Specificity: Recognizes a protein of 30-33 kDa, which is identified as CD20. It is a non-Ig differentiation antigen of B-cells and its expression is restricted to normal and neoplastic B-cells, being absent from all other leukocytes and tissues. CD20 is expressed by pre-B-cells and persists during all stages of B-cell maturation but is lost upon terminal differentiation into plasma cells. This MAb can be used for immunophenotyping of leukemia and malignant cells, B lymphocyte detection in peripheral blood and B cell localization in tissues. It reacts with the majority of B-cells present in peripheral blood and lymphoid tissues and their derived lymphomas. In lymphoid tissue, germinal center blasts and B-immunoblasts are particularly reactive. It is a reliable antibody for ascribing a B-cell phenotype in known lymphoid tissues. Rarely, CD20-positive T-cell lymphomas have been reported. Reactivity has also been noted with Reed-Sternberg cells in cases of Hodgkin s disease, particularly of lymphocyte predominant type.

Purification: 200ug/ml of recombinant MAb purified by Protein A/G.

Immunogen: A recombinant fragment (around aa 213-297) of human MS4A1 protein (exact sequence is proprietary)

Isotype: IgG2b, kappa

Application Details

Application Notes:
