Detection of Human Phospho-VEGF R1/Flt‑1 (Y1213) by Western Blot. Western blot shows lysates of HUVEC human umbilical vein endothelial cell untreated (-) or treated (+) with 100 μM pervanadate (PV) for 10 minutes. PVDF membrane was probed with 1 µg/mL of Rabbit Anti-Human Phospho-VEGF R1/Flt‑1 (Y1213) Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4170), followed by HRP-conjugated Anti‑Rabbit IgG Secondary Antibody (Catalog # HAF008). A specific band was detected for Phospho-VEGF R1/Flt‑1 (Y1213) at approximately 180 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: VEGF R1/Flt-1
VEGF R1, also known as Flt-1, is a receptor tyrosine kinase that contains seven Ig-like repeats in its extracellular domain, a single transmembrane region, and a kinase domain in the intracellular region. Ligand binding induces autophosphorylation on multiple intracellular tyrosine residues. Y1213 is a major binding site for PI3K, Nck, and SHP-2.
