Mouse LpPLA2 (Phospholipase A2, Lipoprotein Associated) Microsample 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 Mouse LpPLA2. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Mouse LpPLA2. 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 Mouse LpPLA2, 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 Mouse LpPLA2 in the samples is then determined by comparing the OD of the samples to the standard curve.Detection Range: 3.13-200 ng/mL. Sensitivity: 0.132 ng/mL. Assay Type: Sandwich. Standard: 200 ng/mL. Sample Type: sSerum, plasma, tissue homogenates and other biological fluids.. Assay duration: 3.5h. Protein Function: Lipoprotein-associated calcium-independent phospholipase A2 involved in phospholipid catabolism during inflammatory and oxidative stress response (PubMed:10066756, PubMed:18434304). At the lipid-aqueous interface, hydrolyzes the ester bond of fatty acyl group attached at sn-2 position of phospholipids (phospholipase A2 activity) (PubMed:10066756, PubMed:18434304). Specifically targets phospholipids with a short-chain fatty acyl group at sn-2 position. Can hydrolyze phospholipids with long fatty acyl chains, only if they carry oxidized functional groups (By similarity). Hydrolyzes and inactivates platelet-activating factor (PAF, 1-O-alkyl-2-acetyl-sn-glycero-3-phosphocholine), a potent pro-inflammatory signaling lipid that acts through PTAFR on various innate immune cells (PubMed:10066756, PubMed:18434304). Hydrolyzes oxidatively truncated phospholipids carrying an aldehyde group at omega position, preventing their accumulation in lipoprotein particles and uncontrolled pro-inflammatory effects (By similarity). As part of high-density lipoprotein (HDL) particles, can hydrolyze phospholipids having long-chain fatty acyl hydroperoxides at sn-2 position and protect against potential accumulation of these oxylipins in the vascular wall (By similarity). Catalyzes the release from membrane phospholipids of F2-isoprostanes, lipid biomarkers of cellular oxidative damage (By similarity) [The Uniprot Consortium]
