Specifications

Isoprostanes are prostaglandin-like compounds that are produced by free radical mediated peroxidation of lipoproteins. This kit is for the quantification of a representative isoprostane, 15-isoprostane F2t (also known as 8-epi-PGF2 or 8-iso-PGF2) Levels of 15-isoprostane F2t in biological fluids have been shown to be useful for assessment of oxidant stress in vivo. 15- isoprostane F2t has also been shown to be a potent vasoconstrictor in rat kidneys and rabbit lungs, and plays a causative role in atherogenesis. Elevated isoprostane levels are associated with hepatorenal syndrome, rheumatoid arthritis, atherosclerosis, and
carcinogenesis.
Catalog #I9050
This kit can be used for the quantification of free 15-isoprostane F2t in urine, plasma, serum or tissue samples following solid phase extraction of the isoprostane-containing fraction. Instructions are also provided for the quantification of total 15-isoprostane F2t following hydrolysis of phospholipids.
PrincipleThis kit is a competitive ELISA for determining levels of 15-isoprostane F2t in biological samples. Briefly, 15-isoprostane F2t in the samples or standards competes with 15-isoprostane F2t conjugated to HRP (HRP) for binding to a polyclonal antibody specific for 15-isoprostane F2t coated on the microplate. The HRP activity results in color development when substrate is added, with the intensity of the color proportional to the amount of 15-isoprostane F2t bound and inversely proportional to the amount of unconjugated 15-isoprostane F2t the samples or standards.
