Western blot analysis was performed on whole cell extracts (30 ug lysate) of HT-29 (Lane 1), HT-29 Serum Starved followed by treatment for 10 minutes with 100 ng/ml of SCF (Lane 2), CaCo-2 (Lane 3) and CaCo-2 Serum Starved followed by treatment for 10 minutes with 100 ng/ml of SCF (Lane 4). The blots were probed with Anti-VEGF Receptor 2 [pY1214] Rabbit Polyclonal Antibody (Product# 441052, 0.35-1 ug/ml) and detected by chemiluminescence using Goat anti-Rabbit IgG (H+L) Secondary Antibody, HRP conjugate (Product # G21234,1:5000 dilution). A 151 kDa band corresponding to VEGF Receptor 2 [pY1214] was enhanced upon treatment across the cell lines tested. Known quantity of protein samples were electrophoresed using Novex® NuPAGE®10 % Bis-Tris gel (Product # NP0301BOX), XCell SureLock™ Electrophoresis System (Product # EI0002) and Novex® Sharp Pre-Stained Protein Standard (Product # LC5800). Resolved proteins were then transferred onto a nitrocellulose membrane with overnight wet transfer system. The membrane was probed with the relevant primary and secondary Antibody following blocking with 5 % skimmed milk. Chemiluminescent detection was performed using Novex® ECL Chemiluminescent Substrate Reagent Kit (Product # WP20005).

Flk-1/KDR vascular endothelial growth factor receptor 2, a cell membrane receptor kinase, is a high affinity receptor for vascular endothelial growth factor and is putatively involved in the growth of endothelial cells and angiogenesis. It contains seven immunoglobulin like sequences in the extracellular domain and exhibits sequence similarity to Flt-1 and Flt-4.
