Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Asp430 of human CD21/CR2 protein. Antibodies are purified by protein A and peptide affinity chromatography.
Background
Complement receptor type 2 (CD21/CR2) is a type 1 transmembrane glycoprotein whose expression is largely restricted to B lymphocytes and follicular dendritic cells (1,2). Research studies have shown that CD21/CR2 functions to bind the complement fragments iC3b, C3dg, and C3d, which function to activate the alternative complement pathway and MAC formation (3,4). In addition to its function as a complement receptor, CD21/CR2 also functions as the B lymphocyte receptor for Epstein-Barr virus (5) and interferon alpha (6). Research studies have also shown that CD21/CR2 participates in B cell activation, proliferation, and protection from apoptosis through its association with components of the B cell coreceptor signaling complex such as CD19 and CD21 (7-9).

Species Reactivity
Species reactivity is determined by testing in at least one approved application (e.g., western blot).
Western Blot Buffer
IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v BSA, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.
