Mouse monoclonal antibody raised against native CR2.
Native purified CR2 from human B-lymphoblastoid cell line IM9.CR2.
Theoretical MW (kDa):
Bovine, Human, Pig
This antibody reacts with CD21 (CR2), a 145 KDa transmembrane glycoprotein (complement C3d receptor - C3dR) expressed on B lymphocytes, follicular dendritic cells, some epithelial cells and a subsets of T lymphocytes. It is not expressed on immature B cells.

Complement component receptor-2 (CR2) is the membrane protein on B lymphocytes to which the Epstein-Barr virus (EBV) binds during infection of these cells. See also CR1 (MIM 120620). Yefenof et al. (1976) [PubMed 181330] found complete overlapping of EBV receptors and C3 (MIM 120700) receptors on human B lymphocytes.[supplied by OMIM
