Anti-CR2 [21A/5]

Invented by Dr Jacqueline Cordell at University of Oxford

Info

Catalogue Number 151354
Applications FACS IHC
Antigen/Gene or Protein Targets Complement component (3d/Epstein Barr virus) receptor 2 (CR2, CD21)
Synonyms Complement Component 3d Receptor 2; Epstein-Barr Virus Receptor 2; Complement C3d Receptor; EBV Receptor; C3DR; CD21 Antigen; CVID7; SLEB9; CD21; Cr2; CR
Reactivity Human
Relevance Monoclonal antibody directed against CR2, involved in allergic responses and inflammatory diseases.

Background and Research Application
CR2 is expressed strongly on mature B cells, follicular dendritic cells and weakly on immature thymocytes and T lymphocytes. In B-cell ontogeny, CR2 appears after the pre-B-stage, is maintained during peripheral B-cell development and is lost upon terminal differentiation into plasma cells. CR2 expression is also gradually lost after stimulation of B cells in vitro. CR2 functions as a receptor for C3d, C3dg and iC3b Complement components and for EBV and for IFN alpha. CR2 binds to CD23 and associates with CD19, CD81 and Leu13 to form a large signal-transduction complex involved in B-cell activation. By inducing release of proinflammatory cytokines and upregulating expression of molecules involved in antigen presentation, CR2 modulates critical monocyte functions that may be relevant to allergic and inflammatory disorders.
Host Mouse
Immunogen CD21
Immunogen UniProt ID P20023
Subclass IgG1 kappa
Myeloma Used P3/NS1/1-Ag4.1
Recommended Growing Conditions RPMI 1640 + 10% FCS + penicillin (100U/ml) + streptomycin (100mg/l) + glutamine (2mM) + HAT
Notes Production Details
Purified using multi-step affinity chromatography with protein A.

Storage Conditions
Store at -20 degrees frozen. Avoid repeated freeze/thaw cycles.

Points of Interest
Genetic variations in the CD21 gene are associated with susceptibility to systemic lupus erythematosus type 9 (SLEB9). Alternatively, spliced transcript variants encoding different isoforms of CD21 have been found.

Ultroser G can be used at 1% if the cells are not growing well.

Concentration
1mg/ml as standard
Research Area Cell Signaling & Signal Transduction, Immunology
