CD21/CD35 Rat anti-Mouse, FITC, Clone: 7G6, BD

Description

• The 7G6 antibody recognizes an epitope shared by 145-150-kDa and 190-kDa complement receptor proteins, originally designated CR2 (CD21) and CR1 (CD35), respectively
• In the mouse, CD21 and CD35 are expressed on the majority of peripheral B lymphocytes, on the majority of resident peritoneal macrophages and mast cells, on peripheral blood granulocytes after treatment with N-formyl-Met-Leu-Phe, and on follicular dendritic cells, but not on thymocytes, T cells, erythrocytes, or platelets
• CD21 is a ligand-binding component of the CD19/CD21/CD81 signal-transduction complex associated with the antigen receptor on B lymphocytes
• CD21/CD35 also co-localizes with CD19 on the surface of peritoneal mast cells.Cr2null mice display impaired inflammatory and humoral immune responses in vivo
• The 7G6 mAb has been reported to inhibit rosette formation by C3d-bearing sheep erythrocytes, to block the complement dependent trapping of immune complexes by follicular dendritic cells, and to down-regulate mouse CD21/CD35 expression upon in vivo application, thus inhibiting primary antibody responses to immunization
• Co-stimulation of B-cell differentiation via Sepharose-coupled 7G6 antibody has also been observed
• The 7G6 mAb recognizes an epitope on CD35 distinct from the epitope recognized by anti-mouse CD35, clone 8C12 (Cat
• No
• 558768, for the purified antibody), and it does not block binding of 8C12 mAb to mouse CD35.
