Product Information

Product Usage Information

Application Dilution
IHC Leica Bond 1:4000 - 1:16000
Immunohistochemistry (Paraffin) 1:2000 - 1:8000

Storage

Supplied in 10 mM PBS containing 0.05% BSA and 0.05% sodium azide. Stable for 36 months when stored at -20°C. This product will freeze at -20°C so it is recommended to aliquot into single-use vials to avoid multiple freeze/thaw cycles. A slight precipitate may be present, but will not interfere with antibody performance.

Specificity / Sensitivity

CD20 (L26) Mouse mAb recognizes endogenous levels of total CD20 protein.

Species Reactivity:

Human, Monkey

Source / Purification

Monoclonal antibody is produced by immunizing animals with human tonsil B cells.

Background

B-lymphocyte antigen CD20 (also known as MS4A1; Membrane-spanning 4-domains subfamily A member 1) is a cell surface phosphoprotein involved in the regulation of B cell activation and proliferation (1,2). 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 (1-3). Evidence suggests that CD20 is necessary for store operated calcium (SOC) entry, which leads to elevated cytoplasmic calcium levels required for B cell activation (4,5). 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 (6).
