VEGF164 Protein, Rat (P.pastoris)
Based on 1 Customer Validation
The VEGF164 protein is a growth factor critical for vasculogenesis, vasculogenesis, and endothelial cell growth, inducing proliferation, promoting migration, inhibiting apoptosis, and enhancing vascular permeability. It binds to FLT1/VEGFR1, KDR/VEGFR2, heparan sulfate, heparin, NRP1 and DEAR/FBXW7-AS1 receptors. VEGF164 Protein, Rat (P.pastoris) is the recombinant rat-derived VEGF164 protein, expressed by P. pastoris , with tag free and A36T mutation.
- Species: Rat
- Source: P. pastoris
-
Storage:Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Background
VEGF164, a growth factor with pivotal roles in angiogenesis, vasculogenesis, and endothelial cell growth, orchestrates a range of cellular responses crucial for vascular development. It stimulates endothelial cell proliferation, facilitates cell migration, prevents apoptosis, and enhances blood vessel permeability by binding to receptors such as FLT1/VEGFR1 and KDR/VEGFR2, as well as heparan sulfate and heparin. During lactation, VEGF164 may contribute to increased vascular permeability, supporting efficient transport of molecules for milk protein synthesis. Additionally, its interaction with the NRP1 receptor initiates signaling pathways essential for motor neuron axon guidance and cell migration, underscoring its involvement in embryonic development processes. Existing as a homodimer with disulfide linkage, VEGF164 also forms a heterodimer with PGF and interacts with isoform 2 of BSG, revealing its multifaceted molecular interactions.
Verified Bioactivity
1.Rat VEGFR-1 (HY-P73552) immobilized on CM5 Chip can bind Rat VEGF164 with an affinity constant of 16.4 pM as determined in a SPR assay.
2.Immobilized Rat VEGF 164 at 2 μg/mL (100 μL/well) can bind Mouse VEGFR2-Fc. The ED50 of Mouse VEGFR2-Fc is 20-30 ng/mL.

Product Properties
Lyophilized powder
Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.
<1 EU/μg, determined by LAL method.
It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).
Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.
Room temperature in continental US; may vary elsewhere.
