Monoclonal Anti-Vascular Endothelial Growth Factor Receptor-1 antibody can be used in several immunochemical assays like immunohistochemistry, immunocytochemistry and immunoprecipitation for the localization of VEGF-R1.
Vascular Endothelial Growth Factor Receptor-2 (VEGF R2) is a 160-200kD protein that belongs to protein kinase superfamily and is expressed mainly on the surface of various endothelial cells. It plays a pivotal role in the regulation of angiogenesis, cell migration, cell survival and cancer cell invasion. ASV derived from VEGF receptor type 1 serve as a potential therapeutics for rheumatoid arthritis. Monoclonal Anti-Vascular Endothelial Growth Factor Receptor-1antibody can be used in western blotting (diluted 1:500) using VEGF Receptor-1 (Flt-1)/Fc Chimera human recombinant. It can also be used in indirect ELISA. Mouse anti-Vascular Endothelial Growth Factor Receptor-1antibody reacts specifically with an epitope within amino acids 1-251 of the extracellular domain of human VEGF Receptor-1 but not with VEGF Receptor-2 (KDR). The product has shown cross reactivity with the mouse Flt1 receptor.
The mitogenic activity of VEGF appears to be stimulated by specific VEGF receptors (160-200 kDa) which can be found on the surface of various endothelial cells. VEGF binds to two structurally similar receptor tyrosine kinases; Flt1 (fms-like tyrosine kinase 1, also known as VEGF Receptor-1 (VEGF-R1), and KDR (kinase insert domain containing receptor, also known as VEGF-R2). Studies using KDR and Flt1 stably transfected endothelial cell lines have shown th at these two receptors exhibit different affinities to VEGF and mediate different responses. KDR/Flk1 does not respond to placental growth factor (PlGF), a VEGF related growth factor, while Flt1 binds PlGF specifically. Flt1 is predominately expressed in human placenta and human vascular endothelial cells. Both VEGF receptors (KDR and Flt1) are upregulated in human fetal and adult kidney.', 'Vascular endothelial growth factor (VEGF) stimulates the proliferation of endothelial cells isolated from both small and large vessels.
