Abcam’s Direct 8-iso-PGF2alpha in vitro competitive ELISA (Enzyme-Linked Immunosorbent Assay) kit is designed for the accurate quantitative measurement of 8-iso-PGF2α in 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-8-iso-PGF2alpha antigen and a rabbit polyclonal antibody specific to 8-iso-PGF2alpha. 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 8-iso-PGF2alpha captured in the plate.
The 8-epimer of Prostaglandin F2α (8-iso-PGF2α) is produced in vivo by both non-cyclooxygenase and cyclooxygenase dependent mechanisms from arachidonic acid. 8-iso-PGF2α has been shown to be a potent vasoconstrictor, a potential mediator of hepatorenal syndrome and atherosclerosis and a mutagen in 3T3 cells and in vascular smooth muscle cells. It has also been postulated to participate as a pathophysiological mediator and is able to modify the fluidity and integrity of membranes. 8-isoPGF2α has been shown to circulate in plasma and is excreted in urine. Methods for assessing total 8-iso-PGF2α typically require the alkaline hydrolysis of 8-iso-PGF2α esters from tissues, followed by length procedures involving extractions, phase separations and thin layer chromatography.
