VEGF Receptor 1 (vascular endothelial growth factor receptor 1 or VEGFR1; also called Flt1 in mouse) is a tyrosine-protein kinase which acts as a cell-surface receptor for VEGFA, VEGFB and PGF ligands for playing an essential role in the embryonic vasculature development and regulation of angiogenesis (normal as well as cancerous tissues), cell survival, migration, macrophage function, chemotaxis, and tumor invasion. VEGFR1 is a 180-185 kD glycoprotein expressed primarily in vascular endothelial cells and also found in a wide range of non-endothelial cells, such as monocytes and macrophages, human trophoblasts, renal mesangial cells, vascular smooth muscle cells, dendritic cells and different human tumour cell types. Interestingly, VEGFR1 acts as a negative regulator of embryonic angiogenesis by inhibiting excessive proliferation of endothelial cells, whereas it promotes endothelial cell proliferation, survival and angiogenesis in adults. VEGFR1 expression is regulated by hypoxia through HREs in VEGFR1 promoter. It exists in an inactive conformation in the absence of bound ligand and binding of VEGFA, VEGFB or PGF leads to its dimerization followed by tyrosine residue autophosphorylation mediated activation. VEGFR1 phosphorylation sites includes Tyr794, Tyr1169, Tyr1213, Tyr1242, Tyr1327, Tyr1333 etc. and VEGFR1 phosphorylation pattern depends on the ligand, e.g. PlGF, but not VEGFA, induces phosphorylation of Tyr1309. VEGFR1 has been shown to exert its diverse biological activities through its effects on multiple signal transduction pathways including VEGF, KDR, PLCG, PI3K, MAPK etc.

FAQs for VEGFR1/Flt-1 Antibody (NB100-527). (Showing 1 - 2 of 2 FAQs).
I am studying the regulation of PLCg during fertilization in the starfish. I am interested in trying your anti-FLT1 polyclonal antibody. Your information sheet says that the immunogen for this antibody is "A synthetic peptide corresponding to a sequence in the middle region of human FLT1". Since I will be using this antibody in starfish eggs, I compared the starfish protein sequence to the human protein sequence and found areas of high identity between the two and I want to use an antibody that is expected to bind to amino acids common to both. Therefore, I would like some more information to match the immunogen to the starfish protein. Can you tell me specifically which amino acids of human FLT1 were used to make the antibody?
The immunogen sequence to this product is proprietary. I can tell you it falls between amino acids 800-900 of the mouse FLT1 protein [UniProt# P35969].
Would you be able to tell me the concentration of the current lot of NB100-527 - VEGFR1/VEGFR2 Ab?
The concentration calculator allows you to quickly calculate the volume, mass or concentration of your vial. Simply enter your mass, volume, or concentration values for your reagent and the calculator will determine the rest.
