Quantity:96T. Other Quantitys are also available. Please Inquire. Reactivity:Pig (Sus scrofa; Porcine) UniProt:P49151 Abbreviation:VEGFA Alternative Names:RP1-261G23.1; MGC70609; MVCD1; VEGF; VEGF-A; VPF; vascµLar endothelial growth factor isoform VEGF165|vascµLar permeability factor Application:ELISA Range:4.69-300 pg/mL Sensitivity:1.17 pg/mL Intra-AssayCV:≤4.6% Inter-AssayCV:≤10.2% Recovery:1,05 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 VEGFA in samples. An antibody specific for VEGFA has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyVEGFA present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjµgated antibody specific for VEGFA 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 VEGFA bound in the initial step. The color development is stopped and the intensity of the color is measured. Product Overview:This gene is a member of the PDGF/VEGF growth factor family and encodes a protein that is often found as a disµLfide linked homodimer. This protein is a glycosylated mitogen that specifically acts on endothelial cells and has various effects, including mediating increased vascµLar permeability, inducing angiogenesis, vascµLogenesis and endothelial cell growth, promoting cell migration, and inhibiting apoptosis. Elevated levels of this protein is linked to POEMS syndrome, also known as Crow-Fukase syndrome. Mutations in this gene have been associated with proliferative and nonproliferative diabetic retinopathy. Alternatively spliced transcript variants, encoding either freely secreted or cell-associated isoforms, have been characterized. There is also evidence for the use of non-Aµg (Cµg) translation initiation sites upstream of, and in-frame with the first Aµg, leading to additional isoforms. 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).
