VEGF165 Protein, Human, Recombinant (His & Avi), Biotinylated

Vascular endothelial growth factor (VEGF), also known as vascular permeability factor (VPF) and VEGF-A, is a potent mediator of both angiogenesis and vasculogenesis in the fetus and adult. It is a member of the platelet-derived growth factor (PDGF)/vascular endothelial growth factor (VEGF) family and often exists as a disulfide-linked homodimer. VEGF-A protein is a glycosylated mitogen that specifically acts on endothelial cells and has various effects, including mediating increased vascular permeability, inducing angiogenesis, vasculogenesis and endothelial cell growth, promoting cell migration, inhibiting apoptosis and tumor growth. VEGF-A protein is also a vasodilator that increases microvascular permeability, thus it was originally referred to as vascular permeability factor.Cancer ImmunotherapyImmune CheckpointImmunotherapyTargeted Therapy

The ED50 for this effect is typically 4-16 ng/mL. 2.Loaded Avastin on ProA Biosensor, can bind Biotinylated Human, Cynomolgus VEGF protein, His & AVI Tag with an affinity constant of 0.443nM as determined in BLI assay (Routinely tested).

Description

Species	Human,Cynomolgus
Expression System	HEK293
Tag	His,AVI
Accession Number	P15692-4
Synonyms	vascular endothelial growth factor A
Construction	A DNA sequence encoding the human, Cynomolgus VEGF165 (P15692-4) (Ala27-Arg191) was expressed with a C-terminal AVI tag followed by a polyhistidine tag. The expressed protein was biotinylated in vivo by the Biotin-Protein ligase (BirA enzyme) which is co-expressed.
Protein Purity	> 95 % as determined by SDS-PAGE.
Molecular Weight	Approxiamtely 23.1 kDa

Endotoxin	< 1.0 EU per μg of the protein as determined by the LAL method.
Formulation	Lyophilized from sterile PBS, pH 7.4. Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0. 01% Tween 80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hard copy of CoA.
Reconstitution	A hardcopy of datasheet with reconstitution instructions is sent along with the products. Please refer to it for detailed information.
Stability & Storage	Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃. Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
Shipping	In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
