Description

Molecular weight: Recombinant human full length VEGF is a 38.2 kDa homodimeric protein consisting of two 165 amino acid polypeptide chains (amino acids 27-191 P15692-4 VEGFA_HUMA) with His tag at N-terminal.

Description: Vascular endothelial growth factor is a member of the platelet-derived growth factor family. It is a specific mitogen for vascular endothelial cells in vitro and a strong angiogenic factor in vivo. Induces endothelial cell proliferation, promotes cell migration, inhibits apoptosis and induces permeabilization of blood vessels. Expressed in vascularized tissues, VEGF plays a prominent role in normal and pathological angiogenesis. In addition to its action as a mitogen it is a potent vascular permeability
factor (VPF) in vivo and is also a chemo attractant for monocytes cells.
VEGF binds to the FLT1/VEGFR1 and KDR/VEGFR2 present on endothelial cells. Substantial evidence implicates VEGF in the induction of tumor metastasis by stimulating the production of matrix metalloproteinases (MMPs).

2. Recombinant human  VEGF 165a shows effect on kerotinocytes cell proliferation (HaCaT cells).The activity is determined by the dose-dependent stimulation of the cell proliferation 48 hours after treatment with recombinant protein. Cell viability was assessed by MTT .  It was observed 30% of cell proliferation with a concentration ˂5ng/ml.
