Anti-CD62L Antibody (DREG-200)
Anti-CD62L Antibody (DREG-200) is a human monoclonal antibody targeting CD62L/L-selectin. Anti-CD62L Antibody (DREG-200) binds to residues 45, 46 and 47 of L-selectin, and blocks L-selectin-mediated interactions, neutrophil rolling, adhesion, aggregation, secondary anchoring, as well as leukocyte rolling on ligands. Anti-CD62L Antibody (DREG-200) reduces myocardial necrosis, coronary endothelial dysfunction, and neutrophil migration driven by neutrophil microparticles. Anti-CD62L Antibody (DREG-200) exerts cardioprotective effects in feline models. Anti-CD62L Antibody (DREG-200) can be used in studies related to myocardial ischemia-reperfusion injury. The recommended isotype control is Mouse IgG1 kappa (HY-P99977).

Anti-CD62L Antibody (DREG-200) (15 μg/106 neutrophils; 0.5-1 h) blocks the enhanced IL-8-induced chemotaxis of isolated human peripheral blood neutrophils by L-NAME (HY-18729A), and inhibits the ability of L-NAME-induced human neutrophil-derived microparticles to enhance IL-8-induced chemotaxis of isolated human peripheral blood neutrophils[1].
Anti-CD62L Antibody (DREG-200) (at saturated concentration; incubated at 4°C for 30 min) detects the expression of L-selectin on human neutrophil-derived microparticles[1].
Anti-CD62L Antibody (DREG-200) (40 μg/mL; 30 min) specifically binds to unstimulated feline neutrophils[2].
Anti-CD62L Antibody (DREG-200) (10-40 μg/mL; 5 min PMN preincubation, 20 min incubation at 4°C) inhibits the adhesion of unstimulated feline polymorphonuclear leukocytes (PMN) to ischemic/reperfused feline coronary vascular endothelium in a concentration-dependent manner, while exerting no effect on their adhesion to normal endothelium[2].
Anti-CD62L Antibody (DREG-200) blocks L-selectin-mediated rolling of primary human blood lymphocytes on immobilized PSGL-1-Fc under flow conditions[3].
Anti-CD62L Antibody (DREG-200) blocks L-selectin-mediated rolling of Jurkat cells on immobilized PSGL-1-Fc, E-selectin-Fc, PNAd and sLex-PAA under flow conditions[3].
