Immunofluorescence analysis of Phospho-VEGF Receptor 2 pTyr1054 / pTyr1059 was done on 90% confluent log phase HUVEC cell treated with 100ng of VEGF for 30 minutes. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 10 minutes, and blocked with 1% BSA for 1 hour at room temperature. The cells were labeled with Phospho-VEGF Receptor 2 pTyr1054 / pTyr1059 Rabbit Polyclonal Antibody (441047G) at 1:250 dilution in 0.1% BSA and incubated for 3 hours at room temperature and then labeled with Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate (Product # A27034) at a dilution of 1:2000 for 45 minutes at room temperature (Panel a: green). Nuclei (Panel b: blue) were stained with SlowFade® Gold Antifade Mountant with DAPI (S36938). F-actin (Panel c: red) was stained with Rhodamine Phalloidin (Product # R415, 1:300). Panel d is a merged image showing punctuated membranous localization. Panel e is untreated cell with no signal. Panel f is a no primary antibody control. The images were captured at 60X magnification.

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.
