产品描述

Lipoxin B4 (LXB4) is a positional isomer of LXA4 produced by the metabolism of 15-HETE or 15(S)-HpETE by human leukocytes. At a concentration of 100 nM, LXB4 inhibits polymorphonuclear leukocyte (PMN) migration stimulated by leukotriene B4 and inhibits LTB4-induced adhesion of PMNs with an IC50 value of 0.3 nM.
