Anti-CD21L [R4/23] rAb

Tool Details

*FOR RESEARCH USE ONLY

• Name: Anti-CD21L [R4/23] rAb
• Alternate name: Complement Component (3d/Epstein Barr Virus) Receptor 2; Epstein-Barr Virus Receptor 2; Complement C3d Receptor 3; EBV Receptor 3; C3DR 3; CD21 Antigen; CVID7; SLEB9; CD21; Cr2
• Clone: R4/23
• Tool sub type: Primary antibody
• Class: Recombinant
• Conjugation: Unconjugated
• Reactivity: Human
• Host: Mouse
• Application: WB
• Description: CR2 is expressed strongly on mature B cells, follicular dentritic cells and weakly on immature thymocytes and T lymphocytes. CR2 functions as a receptor for C3d, C3dg and iC3b Complement components and for EBV and for IFN alpha. Follicular dendritic cells (contained in B cell follicles) selectively express the “Long” isoform of CR2 (CD21L) that contains an additional exon (10a) compared to CR2 (CD21). R4/23 recognises the long form of CR2 and can be used to identify dendritic reticulum cells (or their remnants) in lymphoid tissues.
• Immunogen: Cell lysate from a chronic lymphocytic leukemia patient.
• Isotype: IgM

Target Details

• Target: Complement component (3d/Epstein Barr virus) receptor 2; long form (CR2, CD21L)
