Human CD21/CR2 ELISA Kit

Product Description

Human CD21/CR2 ELISA Kit - 1 Kit (96 Wells)

Our Human CD21/CR2 ELISA Kit is a sandwich ELISA intended for the quantitative determination of human CD21 in cell culture supernates, serum and plasma (heparin, EDTA).

Complement receptor type 2(CR2), also known as C3DR or CD21, is a protein that in humans is encoded by the CR2 gene. It is mapped to 1q32.2. CR2 is involved in the complement system. It binds to iC3b(inactive derivative of C3b), C3dg, or C3d. CR2 is the membrane protein on B lymphocytes to which the Epstein-Barr virus (EBV) binds during infection of these cells. CR2, together with CD19, CD81, and CD225, forms the B-cell coreceptor complex, which lowers the activation threshold of the B-cell antigen receptor. Genetic variations in this gene are associated with susceptibility to systemic lupus erythematosus type 9 (SLEB9).
