Attributs du produit: The 2F1 monoclonal antibody specifically binds to KLRG1 (Killer cell Lectin-like Receptor G1), which is the mouse homologue of the rat mast cell function-associated antigen (MAFA), on all mouse strains tested (eg, AKR/J, BALB/c, C3H/HeN, C3H.SW, C57BL/6, DBA/1, SJL, 129/J). Unlike rat MAFA, which is expressed on mast cells, mouse KLRG1 is expressed on a large subset of NK cells, lymphokine-activated killer (LAK) cells, adherent LAK (A-LAK) cells, subsets of activated CD8+ T lymphocytes, and small fractions of CD4+ and CD8+ T cells, but not mast cells. The expression of KLRG1 is correlated with reduced proliferative capacity of activated T lymphocytes or reduced effector functions of activated NK cells. This molecule is believed to play a common role in the regulation of leukocytes of both the innate and adaptive immune system. It has been observed that the 2F1 mAb stains the rat basophilic leukemia cell line, RBL-2H3, which is known to express MAFA. The KLRG1 protein is an inhibitory lectin-like type II transmembrane receptor containing a cytoplasmic motif similar to ITIM (Immunoreceptor Tyrosine-based Inhibitory Motif), its ligand has not been identified KLRG1 is expressed mainly as a homodimeric molecule consisting of two N-glycosylated subunits of approximately 30-38 kDa. The level of KLRG1 expression is reduced in MHC class I-deficient mice, although direct binding of KLRG1 to MHC class I antigens could not be detected. Cross-linking of KLRG1 by 2F1 mAb reduces TCR-mediated Ca++ mobilization and cytotoxic responses (but not IFN-γ production) by CD8+ T cells and inhibits IFN-γ and TNF-α production and redirected lysis by NK cells. Flow cytometric analysis of KLRG1 expression on mouse splenocytes. C57BL/6 splenocytes were preincubated with Mouse BD Fc Block™ purified anti-mouse CD16/CD32 mAb 2.4G2 (Cat. No. 553141/553142), then stained with a FITC mouse anti-mouse NK-1.1 antibody (Cat.No. 553164/561082) in conjunction with either a Biotin Hamster IgG2, κ Isotype Control (Cat. No. 550084, Left Panel) or the Botin Hamster anti-Mouse KLRG1 antibody (Cat.No. 550863, Right Panel) followed by Streptavidin-PE (Cat. No. 554061). Dot plots were derived from gated events based on forward and side light-scatter characteristics of viable splenocytes. Flow cytometry was performed using a BD™ LSR II flow cytometry system.
