Figure 5From: Binding of ATP to vascular endothelial growth factor isoform VEGF-A165 is essential for inducing proliferation of human umbilical vein endothelial cellsATP induces a conformational change in the secondary structure of VEGF-A 165 . Far-UV CD spectra were recorded of VEGF-A165 (40 μM) pre-incubated without or with ATP (80 μM). Pre-incubation was performed in Tris-HCl (pH 7.5) at 37°C for 15 min.Back to article page
