Human PAFAH2 (Platelet Activating Factor Acetylhydrolase 2) ELISA Kit

The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Human PAFAH2. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human PAFAH2. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Human PAFAH2, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of Human PAFAH2 in the samples is then determined by comparing the OD of the samples to the standard curve. Protein Function: Catalyzes the hydrolyze of the acetyl group at the sn-2 position of platelet-activating factor (PAF) and its analogs, leading to their inactivation (PubMed:9494101). Hydrolyzes propionyl and butyroyl moieties approximately half as effectively as PAF (By similarity). Also catalyzes transacetylation of the acetyl group from platelet-activating factor (PAF) to lysoplasmalogen and to sphingosine, producing plasmalogen analogs of PAF and N-acetylsphingosine (C2-ceramide) respectively. Has a marked selectivity for phospholipids with short acyl chains at the sn-2 position (By similarity) [The Uniprot Consortium]
