Background: B-lymphocyte antigen CD20 is a cell surface phosphoprotein involved in the regulation of B cell activation and proliferation . It is commonly used as a marker to identify B cells and is expressed throughout B cell development, up until their differentiation into plasma cells. CD20 has no known ligand, and its expression and function are largely conserved between human and mouse . Evidence suggests that CD20 is necessary for store operated calcium entry, which leads to elevated cytoplasmic calcium levels required for B cell activation . Anti-CD20 antibody immunotherapy depletes B cells by activation of the innate monocytic network and is a common treatment for B cell lymphomas, leukemias, and autoimmune diseases .

Product: Mouse IgG1. Liquid in PBS, pH 7.3, 30% glycerol, and 0.01% sodium azide.

Purification and Purity: This antibody is purified through a protein G column.

Specificity: Recognizes endogenous levels of CD20 protein.

Note: For research use only, not for use in diagnostic procedure.

Extra Notes: Western blot analysis of CD20 expression in Ramos (A) whole cell lysates., Immunohistochemical analysis of CD20 staining in human tonsil formalin fixed paraffin embedded tissue section. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH 6.0). The section was then incubated with the antibody at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.
