Recombinant Human VEGF₁₂₁ (aa 207-318)

Vascular endothelial growth factor (VEGF), a potent proangiogenic cytokine¹ is the key signal used by oxygen-hungry cells to promote growth of blood vessels. It binds to specialized receptors on the surfaces of endothelial cells and directs them to build new vessels.² The alternative splicing of mRNA from a single 8-exon VEGFA gene results in multiple isoforms which are classified by their terminal exon splice site. The classification depends on whether this terminal exon (exon-8) is proximal or distal. VEGF₁₂₁ refers to the proximal splice site. VEGF are crucial regulators of vascular development during embryogenesis (vasculogenesis) and blood-vessel formation in the adult (angiogenesis). Abnormal VEGF function is associated with inflammatory diseases including atherosclerosis, and hyperthyroidism.^3,4,5,6
