ENPP2 ELISA Kit (Human)

Intra-assay Precision (Precision within an assay) : 3 samples with low, middle and high level Ectonucleotide Pyrophosphatase/Phosphodiesterase 2 (ENPP2) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays) : 3 samples with low, middle and high level Ectonucleotide Pyrophosphatase/Phosphodiesterase 2 (ENPP2) were tested on 3 different plates, 8 replicates in each plate. CV (%) = SD/meanX100 Intra-Assay: CV<10% Inter-Assay: CV<12%

ATX; ATX-X; AUTOTAXIN; autotaxin-t; ectonucleotide pyrophosphatase/phosphodiesterase family member 2; E-NPP 2; extracellular lysophospholipase D; LysoPLD; NPP2; PD-IALPHA; PDNP2; phosphodiesterase I/nucleotide pyrophosphatase 2; plasma lysophospholipase D.

Hydrolyzes lysophospholipids to produce the signaling molecule lysophosphatidic acid (LPA) in extracellular fluids (PubMed:15769751, PubMed:26371182, PubMed:27754931) . Major substrate is lysophosphatidylcholine (PubMed:12176993, PubMed:27754931) . Also can act on sphingosylphosphorylcholine producing sphingosine-1-phosphate, a modulator of cell motility. Can hydrolyze, in vitro, bis-pNPP, to some extent pNP-TMP, and barely ATP (PubMed:15769751, PubMed:12176993) . Involved in several motility-related processes such as angiogenesis and neurite outgrowth. Acts as an angiogenic factor by stimulating migration of smooth muscle cells and microtubule formation (PubMed:11559573) . Stimulates migration of melanoma cells, probably via a pertussis toxin-sensitive G protein (PubMed:1733949) . May have a role in induction of parturition (PubMed:12176993) . Possible involvement in cell proliferation and adipose tissue development (Probable) . Tumor cell motility-stimulating factor (PubMed:1733949, PubMed:11559573) .

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 Ectonucleotide Pyrophosphatase/Phosphodiesterase 2 (ENPP2) . Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Ectonucleotide Pyrophosphatase/Phosphodiesterase 2 (ENPP2) . 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 Ectonucleotide Pyrophosphatase/Phosphodiesterase 2 (ENPP2), 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 Ectonucleotide Pyrophosphatase/Phosphodiesterase 2 (ENPP2) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
