| CD21 is also known as CR2, C3d receptor and EBV receptor. Its epitope maps within 5-8 short consensus repeats (SCRs) of CD21 molecule. CD21 is expressed strongly on mature B cells, follicular dentritic cells, pharyngeal, cervical epithelial cells and weakly on immature thymocytes and T lymphocytes. In B-cell ontogeny, CD21 appears after the pre-B-stage, is maintained during peripheral B-cell development and is lost upon terminal differentiation into plasma cells. CD21 expression is also gradually lost after stimulation of B cells in vitro. CD21 functions as receptor for C3d, C3dg and iC3b Complement components, for EBV and for IFNa. CD21 is also known as Complement Receptor Type 2 (CR2) or Epstein-Barr virus (EBV) receptor. CD21 binds to CD23 and associates with CD19, CD81 and Leu13 to form a large signal-transduction complex involved in B cell activation. | | | Catalog # | C2272-58 | | Recommended Secondary Reagents | F(ab')2 rabbit anti-mouse IgG HRP | | Fusion Partners | Spleen cells from immunized mice were fused with cells of the mouse p3-NS1-Ag4-1 myeloma cell line | | Recommended Negative Controls | Mouse IgG2a Negative Control | | Applications | Immunohistochemistry: (frozen)- 1:10-1:20, (paraffin)- 1:10-1:20 | | Optimal working dilutions to be determined by researcher. | | Immunohistochemistry | Requires antigen retrieval using heat treatment prior to staining of paraffin sections.
