Test Principale: This assay employs a two-site sandwich ELISA to quantitate PAFAH2 in samples. An antibody specific for PAFAH2 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyPAFAH2 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for PAFAH2 is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of PAFAH2 bound in the initial step. The color development is stopped and the intensity of the color is measured.

Product Overview: Platelet-activating factor acetylhydrolase 2, cytoplasmic is a single-subunit intracellular enzyme that catalyzes the removal of the acetyl group at the SN-2 position of platelet-activating factor (identified as 1-O-alkyl-2-acetyl-sn-glyceryl-3-phosphorylcholine) . However, this lipase exhibits a broader substrate specificity than simply platelet activating factor. Two other isoforms of intracellular platelet-activating factor acetylhydrolase exist, and both are multi-subunit enzymes. Additionally, there is a single-subunit serum isoform of this enzyme.PAFAH2 shares approximately 43% identity with plasma PAFAH, but has virtually no similarity to brain PAFAH1B1. Unlike PAFAH, PAFAH2 contains no secretory signal sequence, confirming its intracellular localization.

Stability: The stability of ELISA kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage condition. The loss rate was determined by accelerated thermal degradation test. Keep the kit at 37°C for 4 and 7 days, and compare O.D.values of the kit kept at 37°C with that of at recommended temperature. (referring from China Biological Products Standard, which was calculated by the Arrhenius equation. For ELISA kit, 4 days storage at 37°C can be considered as 6 months at 2 - 8°C, which means 7 days at 37°C equaling 12 months at 2 - 8°C) .
