Tech Info / Data

Background: 

Recombinant human VEGF121, expressed in engineered human cells, belongs to the PDGF/VEGF growth factor family. VEGF121 is a 37 kDa homodimeric, 50 kDa homotrimeric disulfide-linked glycoprotein. Many cell types secrete VEGF and it is a potent angiogenic factor and mitogen that stimulates proliferation, migration and formation of endothelial cells. VEGF stimulates permeabilization of blood vessels and is present in some tumors of the nervous system. VEGF is induced by hypoxia, oncogene mutations and cytokines such as IL-1, IL-8 and TNF-α.
