Leukotriene B4 ELISA kits are assays designed to detect the pro-inflammatory cytokine, leukotriene B4 (LTB4). Synthesized from arachidonic acid, it is one of the most important leukotrienes in acute inflammation. It activates leukocytes and is a chemoattractant for macrophages and neutrophils. It also stimulates the adhesion of leukocytes to the vascular endothelium. LTB4 has been associated with inflammatory diseases such as arthritis.
