anti-CD21 antibody [LB21]
anti-CD21 antibody [LB21] for Flow cytometry,IHC-Frozen sections,Immunoprecipitation and Human,Bovine,Cat,Goat,Sheep
Overview
| Product Description | Mouse Monoclonal antibody [LB21] recognizes CD21 Mouse anti Human CD21 antibody, clone LB21 recognizes the human Complement receptor type 2, also known as CD21 or the Epstein-Barr virus receptor. CD21 is a ~14 kDa cell surface glycoprotein expressed by mature B cells and by follicular dendritic cells. The molecule acts as a receptor for complement components C3d, C3dg and iC3b, as well as for Epstein Barr Virus. It forms part of a large signal transduction complex in association with CD19. |

| Application Note | IHC-Fr: The epitope recognised by this antibody is reported to be sensitive to formaldehyde fixation and tissue processing. Arigo recommends the use of acetone fixation for frozen sections. FACS: Use 10 µl of the suggested working dilution to label 10^6 cells or 100 µl human whole blood. * The dilutions indicate recommended starting dilutions and the optimal dilutions or concentrations should be determined by the scientist. |

|---|---|
| Gene Symbol | CR2 |
| Gene Full Name | complement component (3d/Epstein Barr virus) receptor 2 |
| Background | This gene encodes a membrane protein, which functions as a receptor for Epstein-Barr virus (EBV) binding on B and T lymphocytes. Genetic variations in this gene are associated with susceptibility to systemic lupus erythematosus type 9 (SLEB9). Alternatively spliced transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Sep 2009] |
| Function | Receptor for complement C3Dd, for the Epstein-Barr virus on human B-cells and T-cells and for HNRPU. Participates in B lymphocytes activation. [UniProt] |
| Calculated MW | 113 kDa |
