Product overview
Abcam’s Leukotriene B4 in vitro competitive ELISA (Enzyme-Linked Immunosorbent Assay) kit is designed for the accurate quantitative measurement of Leukotriene B4 (LTB4) in tissue culture media, plasma, urine and saliva.
A goat anti-rabbit IgG antibody has been precoated onto 96-well plates. Standards or test samples are added to the wells, along with an alkaline phosphatase (AP) conjugated-LTB4 antigen and a polyclonal rabbit antibody specific to LTB4. After incubation the excess reagents are washed away. pNpp substrate is added and after a short incubation the enzyme reaction is stopped and the yellow color generated is read at 405 nm. The intensity of the yellow coloration is inversely proportional to the amount of LTB4 captured in the plate.

Notes
Leukotrienes are major products of 5-lipoxygenase metabolism of arachidonic acid. Leukotriene B4 (LTB4) stimulates leukocyte functions including lysosomal enzyme release, adhesion, and aggregation of polymorphonuclear leukocytes. LTB4 has been implicated as a potent mediator of inflammatory diseases and immunoregulation. The cysteinyl leukotrienes (LTC4, LTD4, and LTE4) are formed by addition of cysteine derivatives to LTA4. The conversion of LTA4 to LTC4 by the enzyme LTC4 synthase limits the rate of cysteinyl leukotriene formation. Cysteinyl leukotrienes are potent lipid mediators in inflammation, inducing smooth muscle contractions and increased capillary permeability.
