ELISA Bovine Glycogen phosphorylase, liver form (PYGL)

Reactivity:Bovine (Bos taurus; Cattle) UniProt:Q0VCM4 Abbreviation:PYGL Alternative Names:GSD6; liver glycogen phosphorylase Application:ELISA Range:Request Information Sensitivity:Request Information Intra-AssayCV:?6.1% Inter-AssayCV:?8.4% Recovery:1.04 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 PYGL in samples. An antibody specific for PYGL has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyPYGL present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjµgated antibody specific for PYGL 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 PYGL bound in the initial step. The color development is stopped and the intensity of the color is measured. Product Overview:PYGL is a homodimeric protein switches from inactive phosphorylase B to active phosphorylase A by phosphorylation of serine residue 15. Activity of this enzyme is further regµLated by mµLtiple allosteric effectors and hormonal controls. s have three glycogen phosphorylase isozymes that are primarily expressed in liver, brain and muscle, respectively. The liver isozyme serves the glycemic demands of the body in general while the brain and muscle isozymes supply just those tissues. In glycogen storage disease type VI, or Hers disease, mutations in liver glycogen phosphorylase inhibit the conversion of glycogen to glucose and resµLts in moderate hypoglycemia, mild ketosis, growth retardation and hepatomegaly. 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).
