Vascular endothelial growth factor B also known as VEGF-B is a protein that, in humans, is encoded by the VEGF-B gene. VEGF-B is a growth factor that belongs to the vascular endothelial growth factor family, of which VEGF-A is the best-known member. In contrast to VEGF-A, VEGF-B plays a less pronounced role in the vascular system: Whereas VEGF-A is important for the formation of blood vessels, such as during development or in pathological conditions, VEGF-B seems to play a role only in the maintenance of newly formed blood vessels during pathological conditions. It also plays an important role on several types of neurons. And it is important for the protection of neurons in the retina and thecerebral cortex during stroke and of motoneurons during motor neuron diseases such as amyotrophic lateral sclerosis. Sample Type: Cell culture supernates, serum and plasma (heparin) Intended Use: For quantitative detection of mouse VEGF-B in cell culture supernates, serum and plasma (heparin). Sensitivity: <2pg/ml Range: 31.2-2000pg/ml Specificity: Natural and recombinant mouse VEGF-B Test Principle: This mouse VEGF-B BioAssay(TM) ELISA Kit was based on standard sandwich enzyme-linked immune-sorbent assay technology. A monoclonal antibody from rat specific for VEGF-B has been precoated onto 96-well plates. Standards(sf21,Q20-A207 & Q20-R148) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for VEGF-B is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with PBS or TBS buffer. HRP substrate TMB was used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the mouse VEGF-B amount of sample captured in plate. Kit Components: 96-well plate precoated with mouse VEGF-B antibody, 1 Lyophilized recombinant mouse VEGF-B standard, 10ng/tube*2 Biotinylated mouse VEGF-B antibody, 130ul (dilution 1:100) Avidin-Biotin-Peroxidase Complex (ABC), 130ul (dilution 1:100) Sample diluent buffer, 30ml Antibody diluent buffer, 12ml ABC diluent buffer, 12ml TMB color developing agent, 10ml TMB stop solution, 10ml Storage and Stability: Store powder at 4C liquid at -20C. Store other components at 4C. Stable for at least 6 months For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
