概要
Vascular endothelial growth factor (VEGF-165) is a heparin-binding homodimeric glycoprotein involved in embryonic vasculogenesis and angiogenesis. VEGF binds to VEGFR-1 (R1) and VEGFR-2 (R2), and activates Raf/MEK/ERK and PI3K/AKT pathways (Ferrara et al.). It plays an important role in neurogenesis both in vitro and in vivo (Storkebaum et al.). It has neurotrophic effects on neurons of the central nervous system and promotes growth and survival of dopaminergic neurons and astrocytes. VEGF also promotes growth and survival of vascular endothelial cells, monocyte chemotaxis, and colony formation by granulocyte-macrophage progenitor cells (Ferrara et al.). VEGF-165 contains two polypeptide chains of 165 amino acids each. This product is animal component-free.

Data
(A) The biological activity of Human Recombinant VEGF-165, ACF was tested by the ability to promote the proliferation of HUVECs. Cell proliferation was measured after 88 hours of culture using a fluorometric assay method. The EC50 is defined as the effective concentration of the growth factor at which cell proliferation is at 50% of maximum. The EC50 in the example above is 3.35 ng/mL. (B) Human Recombinant VEGF-165, ACF was resolved with SDS-PAGE under reducing (+) and non-reducing (-) conditions and visualized by Coomassie Blue staining.
