| Biochem/physiol Actions: | Vascular endothelial growth factor 121 (VEGF121) belongs to the PDGF/VEGF growth factor family. 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. |
| General description: | HumanPro VEGF-121(vascular endothelial growth factor 121) is an isoform of VEGFA and is expressed in human HEK 293 cells as a disulfide linked, glycosylated cytokine with an apparent molecular mass of 37 kDa as a homodimer and 50 kDa as a homotrimer. VEGF-A exists in three different isoforms VEGF-121, VEGF165 is an angiogenic properties. Production in human HEK 293 cells offers authentic glycosylation. Glycosylation contributes to stability in cell growth media and other applications. There are five types of VEGF ligands identified in mammals, which exists as different splice variants.VEGFA is a dimeric glycoprotein consisting two monomers antiparallel to each other. |
