CD21 antibody (AA 44-196)

Catalog No. ABIN6939182

Product Details anti-CD21 Antibody

Target: CD21 (CR2) (Complement Component (3d/Epstein Barr Virus) Receptor 2 (CR2))

Binding Specificity: AA 44-196

Reactivity: Human

Host: Mouse

Clonality: Monoclonal

Conjugate: This CD21 antibody is un-conjugated

Application: Immunohistochemistry (IHC), ELISA, Staining Methods (StM), Coating (Coat)

Specificity: Recognizes a protein of 140 kDa, which is identified as the complement receptor 2 (CR2) / CD21. This protein 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. 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 associates with CD19, CD81 and Leu13 to form a large signal-transduction complex involved in B cell activation.

Purification: Purified by Protein A/G

Immunogen: Recombinant fragment (around aa 44-196) of human CR2 (CD21) protein (exact sequence is proprietary)
