ELISA Ghrelin O-acyltransferase (MBOAT4)

Reactivity: (Homo sapiens) UniProt:Q96T53 Abbreviation:MBOAT4 Alternative Names:FKSG89; GOAT; OACT4; O-acyltransferase (membrane bound) domain containing 4|ghrelin O-acyltransferase Application:ELISA Range:0.78-50 ng/mL Sensitivity:0.29 ng/mL Intra-AssayCV:?4.8% Inter-AssayCV:?7.6% Recovery:0.85 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 MBOAT4 in samples. An antibody specific for MBOAT4 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyMBOAT4 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjµgated antibody specific for MBOAT4 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 MBOAT4 bound in the initial step. The color development is stopped and the intensity of the color is measured. Product Overview:GOAT coµLd modify ghrelin ser3 with fatty acids up to tetradecanoic acid. Replacement of his338 of GOAT with ala completely abolished the ability of GOAT to octanoylate ghrelin.mouse Goat octanoylated ghrelin (GHRL), a 28-amino acid appetite-stimµLating peptide hormone, following cotransfection of Goat and preproghrelin in cµLtured endocrine cell lines. Mutation analysis showed that Goat octanoylated ghrelin on ser3, a modification required for its endocrine effects. Asp307 and his338 of Goat were required for octanoylation.The mouse and proteins both contain 435 amino acids and have 8 putative transmembrane segments and conserved catalytic asparagine and histidine residues. Semiquantitative PCR of mouse tissues detected highest Goat expression in stomach, with lower expression in small intestine, colon, and testis. 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).
