Product Overview
This rabbit polyclonal antibody targets vascular endothelial growth factor receptor 1 (gene FLT1) in human samples and is validated for Western blot, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 150.8 kDa, and the supplier reports an observed band at about 150 kDa.
Vascular endothelial growth factor receptor 1 (VEGFR-1, FLT1) is a receptor tyrosine kinase that binds VEGF-A, VEGF-B and placental growth factor. Its kinase signaling is weak, and a soluble form acts largely as a decoy that limits VEGF availability. FLT1 is studied in angiogenesis, macrophage recruitment, preeclampsia and vascular development.
