VEGF Receptor 1 (Flt1, VEGFR1) Soluble (Vascular Endothelial Growth Factor Receptor 1, sVEGFR-1, sFlt1)
Description:
VEGFR-1 (vascular endothelial growth factor receptor 1) is a 180-kDa membrane receptor tyrosine kinase that is the receptor for vascular endothelial growth factor (VEGF), VEGFB and PGF. VEGF is a key regulator of physiological angiogenesis during embryogenesis, skeletal growth and reproductive functions. VEGF has also been implicated in pathological angiogenesis associated with tumors, intraocular neovascular disorders and other conditions. VEGFR-1 has seven extracellular Ig-like domains; the second domain from the N-terminus is necessary and sufficient for high affinity VEGF binding. The biological effects of VEGF are mediated by VEGFR-1 and VEGFR-2, and two major tyrosine phosphorylation sites at Tyr 1213 and Tyr 1242 and two minor tyrosine phosphorylation sites at Tyr 1327 and Tyr 1333 exist in VEGFR-1.

Applications:
Suitable for use in Western Blot, Immunoprecipitation, Immunohistochemistry, ELISA and Immunocytochemistry. Other applications not tested.

Recommended Dilutions:
