ELISA Vasorin (VASN)

Reactivity: (Homo sapiens) UniProt:Q6EMK4 Abbreviation:VASN Alternative Names:SLITL2; slit-like 2 Application:ELISA Range:0.312-20 ng/mL Sensitivity:0.113 ng/mL Intra-AssayCV:?5.3% Inter-AssayCV:?9.2% 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 VASN in samples. An antibody specific for VASN has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyVASN present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjµgated antibody specific for VASN 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 VASN bound in the initial step. The color development is stopped and the intensity of the color is measured. Product Overview:The deduced 673-amino acid protein contains a putative hydrophobic signal sequence, 10 tandem arrays of a leucine-rich repeat, an epidermal growth factor-like domain, a fibronectin type III-like domain, and a short intracellµLar region. In situ hybridization detected mouse vasorin in the tunica media of the proximal ascending aorta, descending thoracic aorta, abdominal aorta, and coronary arteries. In mouse kidney, vasorin was expressed in interstitial cells. expression of vasorin in aortas increased gradually in parallel with the differentiation of vascµLar smooth muscle cells beginning at embryonic day 10.5. Vasorin expressed by transfected Chinese hamster ovary cells showed an apparent molecµLar mass of 110 kD, which shifted following N-glycosidase treatment. Vasorin was expressed on the cell surface and was secreted into the cµLture medium. 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).
