CD21 Antibody

• Catalog Number: orb534078
• Category: Antibodies
• Description: CD21/CR2 is expressed strongly on mature B cells, follicular dendritic 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. This mAb is highly specific to CR2 and shows no cross-reaction with CR1.
