Product Information

Product Description

This Cell Signaling Technology^® antibody retains the antigen-binding Fab regions of the original parent host sequence from which it is engineered. This antibody is expected to exhibit the same species cross-reactivity as CD20 (E3N7O) Rabbit Monoclonal Antibody #70168.

Product Usage Information

Application	Dilution
Immunofluorescence (Frozen)	1:200 - 1:800

Storage

Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/mL BSA, 50% glycerol, and less than 0.02% sodium azide. Store at –20°C. Do not aliquot the antibody.

Protocol

Specificity / Sensitivity

CD20 (E3N7O) Horse Chimeric Monoclonal Antibody recognizes endogenous levels of total CD20 protein.

Species Reactivity:

Mouse, Rat

Source / Purification

This recombinant chimeric antibody is engineered from CD20 (E3N7O) Rabbit Monoclonal Antibody #70168 according to animal-free protocols. The chimeric antibody retains its antigen-binding Fab regions from the original rabbit monoclonal antibody, but contains a horse-derived Fc domain. When multiplexing, Fc-directed rabbit secondaries are required to detect rabbit-host primary antibodies.

The parent antibody, CD20 (E3N7O) Rabbit Monoclonal Antibody #70168, is produced by immunizing animals with a synthetic peptide corresponding to residues near the carboxy terminus of mouse CD20 protein.

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).
