Product overview
Abcam’s 15(S)-HETE in vitro competitive ELISA (Enzyme-Linked Immunosorbent Assay) kit is designed for the accurate quantitative measurement of 15-hydroxyeicosatetraenoic acid in plasma, serum, urine, tissue culture media and other biological fluids.
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-15(S)-HETE antigen and a polyclonal rabbit antibody specific to 15(S)-HETE. 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 15(S)-HETE captured in the plate.

Notes
15(S)-HETE (15-hydroxyeicosatetraenoic acid) is the major hydroxy derivative of arachidonic acid when acted upon by 15-lipoxygenase (15-LOX). It is also the primary monohydroxy acid synthesized by the lipoxygenase activity of Cyclooxygenase-1. Aspirin-mediated acetylation of the COX-1 enzyme results in 15(R)-HETE. Blood platelets, peripheral leukocytes, vascular smooth muscle and other cell types produce Type-1 15-LOX while prostate, lung, skin and cornea tissues produce Type-2. 15-HETE has been proposed to act as a paracrine regulator of smooth muscle and lung neutrophil recruitment due in part to its incorporation into tracheal epithelium at the sn-2 position of phosphatidylinositol. The phosphoinositol modification in turn is thought to affect signal transduction and the regulation of intracellular calcium. Interleukin-4 has been shown to regulate 15(S)-HETE expression and incorporation into cellular phospholipids. 15(S)-HETE binds to actin and the alpha-subunit of mitochondrial ATP synthase suggesting a more direct method in regulating some physiological activities. Increased levels of 15(S)-HETE are associated with asthma, rhinitis, chronic paranasal sinusitis and rheumatoid arthritis.
