• Western Blotting (1 paper)

Monoclonal Anti-Vascular Endothelial Growth Factor antibody produced in mouse was used to block the interaction between VEGF and kinase domain receptor in Calf Pulmonary Aortic Endothelial (CPAE) cells.

Biochem/physiol Actions

The vascular endothelial growth factor family consists of five members, VEGF-A to VEGF-E. They play important roles in important role in embryonic vasculogenesis, angiogenesis and homeostasis. The interaction between VEGFs and their respective receptors results in the activation of MAPK, PI3K, PKC, FAK and Src kinase pathways.
