Test principle: This assay employs a two-site sandwich ELISA to quantitate VASH1 in samples. An antibody specific for VASH1 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyVASH1 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for VASH1 is added to the wells. After washing, Streptavidin conjugated 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 VASH1 bound in the initial step. The color development is stopped and the intensity of the color is measured.

Product Overview: Vasohibin protein contains a cluster of basic amino acids in its C terminus and no classic secretion signal sequence. Vasohibin expression was robust between embryonic weeks 6 to 12 in heart, brain, kidney, lung, skeletal muscle, and whole embryo. Immunohistochemical analysis detected vasohibin at the endothelial layer of placenta and brain. The deduced protein contains 365 amino acids. RT-PCR ELISA detected intermediate expression in adult heart, brain, lung, liver, kidney, ovary, and spinal cord, as well as in fetal brain. Lower expression was detected in skeletal muscle, testis, pancreas, and fetal liver, and little to no expression was detected in spleen. All specific adult brain regions examined showed low to moderate expression.

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 calculated 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).
