ELISA N-acetylglucosaminyl-phosphatidylinositol de-N-acetylase (L)

Reactivity: (Homo sapiens) UniProt:Q9Y2B2 Abbreviation:PIGL Alternative Names:N-acetylglucosaminyl-phosphatidylinositol de-N-acetylase|N-acetylglucosaminylphosphatidylinositol deacetylase|phosphatidylinositol glycan; class L Application:ELISA Range:1.56-100 ng/mL Sensitivity:0.61 ng/mL Intra-AssayCV:?5.6% Inter-AssayCV:?8.6% Recovery:0.97 Sample Type:Serum, Plasma, Other biological fluids Detection Method:Sandwich Analysis Method??:Quantitive Test principle:This assay employs a two-site sandwich ELISA to quantitate PIGL in samples. An antibody specific for PIGL has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyPIGL present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjµgated antibody specific for PIGL is added to the wells. After washing, Streptavidin conjµgated 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 PIGL bound in the initial step. The color development is stopped and the intensity of the color is measured. Product Overview:Glycosylphosphatidylinositol (GPI) is used as a membrane anchor by many eukaryotic cell surface proteins. The first step in GPI biosynthesis involves the transfer of N-acetylglucosamine (GlcNAc) from UDP-GlcNAc to phosphatidylinositol (PI) The second step is de-N-acetylation of GlcNAc-PI. PIGL encodes a deduced 252-amino acid protein that shares 77% identity with the rat protein. Using transfection into mammalian PIGL-deficient cells, Watanabe et al. (1999) demonstrated that S. cerevisiae Gpi12 is the ortholog of and rat PIGL. Disruption of Gpi12 in yeast resµLted in a lethal phenotype. Using purified, recombinant rat PIGL, Watanabe et al. (1999) demonstrated that PIGL has GlcNAc-PI de-N-acetylase activity in vitro, which is enhanced by metal ions. 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 calcµLated 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).
