Nori Human PGE2 ELISA Kit
$461.00 – $832.00
This ELISA kit is for quantification of PGE2 in human. This is a quick ELISA assay that reduces time to 50% compared to the conventional method, and the entire assay only takes 3 hours. This assay employs the quantitative sandwich enzyme immunoassay technique and uses biotin-streptavidin chemistry to improve the performance of the assays. An antibody specific for PGE2 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any PGE2 present is bound by the immobilized antibody. After washing away any unbound substances, a detection antibody specific for PGE2 is added to the wells. Following wash to remove any unbound antibody reagent, a detection reagent is added. After intensive wash a substrate solution is added to the wells and color develops in proportion to the amount of PGE2 bound in the initial step. The color development is stopped, and the intensity of the color is measured.

Background:
The naturally occurring prostaglandin E2 (PGE2) is discovered by Bunting, Gryglewski, Moncada and Vane in 1976, known in medicine as dinoprostone. It has important effects in labour (softening the cervix and causing uterine contraction) and also stimulates osteoblasts to release factors that stimulate bone resorption by osteoclasts. PGE2 is also the prostaglandin that ultimately induces fever. PGE2 also suppresses T cell receptor signaling and may play a role in resolution of inflammation.[1] It works by binding and activating the prostaglandin E2 receptor. Like other prostaglandins, dinoprostone can be used as an abortifacient. It is a direct vasodilator, relaxing smooth muscles, and it inhibits the release of noradrenaline from sympathetic nerve terminals. It does not inhibit platelet aggregation, where PGI2 does. It is also implicated in duct-dependent congenital heart diseases and is used in infusion in order to open the duct although PGE1 is more commonly used.
