Recombinant Human VEGFA

Cat.No.: VEGFA-521H
Product Overview: Recombinant Human VEGF165 Protein (rhVEGF165) Ala207-Arg371 (Accession# NP_001020539) was expressed in human 293 cells (HEK293).
Description: VEGF165 is the most abundant splice variant of VEGF-A. VEGF165 is produced by a number of cells including endothelial cells, macrophages and T cells. VEGF165 is involved in angiogenesis, vascular endothelial cell survival, growth, migration and vascular permeability. VEGF gene expression is induced by hypoxia, inflammatory cytokines and oncogenes. VEGF165 binds to heparan sulfate and is retained on the cell surface and in the extracellular matrix. VEGF165 binds to the receptor tyrosine kinases, VEGFR1 and VEGFR2. VEGF165 is the only splice variant that binds to co-receptors NRP-1 and NRP-2 that function to enhance VEGFR2 signaling. Binding of VEGF165 to VEGFR1 and VEGFR2 leads to activation of the PI3K/AKT, p38 MAPK, FAK and paxillin. VEGF plays a key role in tumor angiogenesis in many cancers.
Source: HEK293
Species: Human
Form: Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally Mannitol or Trehalose are added as protectants before lyophilization.
Bio-activity: The bio-activity was determined by dose-dependent stimulation of the proliferation of HUVEC cells. The ED50<5ng l, corresponding to a specific activity of>2X10^5 Unit/mg.
Molecular Mass: rhVEGF165 contains no "tags"and has a calculated MW of 19 kDa. DTT-reduced protein migrates as a 24 kDa polypeptide and the non-reduced cystine-linked homodimer migrates as a 43 kDa protein.
Endotoxin: Less than 1.0 EU per μg of the rhVEGF165 by the LAL method.
Purity: >98% as determined by SDS-PAGE of reduced (+) and non-reduced (-) rhVEGF165.
Storage: Avoid repeated freeze-thaw cycles. No activity loss was observed after storage at: In lyophilized state for 1 year (4 centigrade-8 centigrade); After reconstitution under sterile conditions for 1 month (4 centigrade-8 centigrade) or 3 months (-20 centigrade to -70 centigrade).
