Isoprostane (8-iso-PGF2a) Urine ELISA Kit, BioAssay

£765.00 1 Kit

Isoprostanes are prostaglandin-like compounds that are produced by free radical mediated peroxidation of lipoproteins. This kit is for the quantification of 15-isoprostane F2t (also known as 8-epi-PGF2a or 8-iso-PGF2a) in urine samples. Levels of 15-isoprostane F2t in urine are useful for the non-invasive 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.

Principle of the Assay:
This kit is a competitive ELISA for determining levels of 15-isoprostane F2t (the best characterized isoprostane) in urine samples. Briefly, urine samples are mixed with an enhanced dilution buffer that essentially eliminates interference due to non-specific binding. The 15-isoprostane F2t in the samples or standards competes with 15-isoprostane F2t conjugated to HRP for binding to a polyclonal antibody specific for 15-isoprostane F2t coated on the microplate. The HRP activity results in colour development when substrate is added, with the intensity of the colour proportional to the amount of 15-isoprostane F2t bound and inversely proportional to the amount of unconjugated 15-isoprostane F2t in the samples or standards.
