CD21 Antibody

Additional Information:
|Introduction CD21 is expressed strongly on mature B cells, follicular dentritic 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 different 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 IFNalpha. CD21 binds to CD23 and assoc with CD19, CD81 and Leu13 to form a large signal-transduction complex involved in B cell activation. | CD21 Monoclonal Antibody Mouse Monoclonal Antibody.
