FLT1/VEGFR1 (Vascular Endothelial Growth Factor Receptor 1) BioAssay(TM) ELISA Kit (Mouse)

Vascular endothelial growth factor receptor 1 is a protein that in humans is encoded by the FLT1 gene. Oncogene FLT belongs to the src gene family and is related to oncogene ROS. Like other members of this family, it shows tyrosine protein kinase activity that is important for the control of cell proliferation and differentiation. This protein binds to VEGFR-A, VEGFR-B and placental growth factor and plays an important role in angiogenesis and vasculogenesis. Expression of this receptor is found in vascular endothelial cells, placental trophoblast cells and peripheral blood monocytes. Multiple transcript variants encoding different isoforms have been found for this gene. Isoforms include a full-length transmembrane receptor isoform and shortened, soluble isoforms. The soluble isoforms are associated with the onset of pre-eclampsia. Sample Type: Cell culture supernates, serum. Intended Use: Sandwich High Sensitivity BioAssay(TM) ELISA kit for Quantitative Detection of Mouse FLT1/VEGFR1. Sensitivity: <10pg/ml, Range: 156pg/ml-10000pg/ml, Specificity: Recognizes natural and recombinant Mouse FLT1/VEGFR1. There is no detectable cross-reactivity with other relevant proteins. Test Principle: This Mouse FLT1/VEGFR1 BioAssay(TM) ELISA Kit was based on standard sandwich enzyme-linked immune- sorbent assay technology. A monoclonal antibody from rat specific for FLT1/VEGFR1 has been precoated onto 96-well plates. Standards(Expression system for standard: NSO, Immunogen sequence: Y23-E759) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for FLT1/VEGFR1 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 FLT1/VEGFR1 amount of sample captured in plate.
