Specifications

Product Data
Species	Human
Expression Host	E. coli
Expression cDNA Clone or AA Sequence	Protein Sequence (showhide) MAPMAEGGGQNHHEVVKFMDVYQRSYCHPIETLVDIFQEYPDEIEYIFKPSCVPLMRCGGCCNDEGLECVPTEESNITMQIMRIKPHQGQHIGEMSFLQHNKCECRPKKDRARQENPCGPCSERRKHLFVQDPQTCKCSCKNTDSRCKARQLELNERTCRCDKPRR with polyhistidine tag at the C-terminus.
Tag	His Tag (C-term)
Predicted MW	The protein has a calculated MW of 20.11 kDa. The protein migrates as 21 kDa under reducing condition (SDS-PAGE analysis).
Purity	>98% as determined by SDS-PAGE.
Buffer	The protein was lyophilized from a 0.2 µm filtered solution containing 1X PBS, pH 8.0.
Applications	Cell culture
Storage	Lyophilized protein should be stored at -20°C for 1 year. Upon reconstitution, store at 2°C to 8°C for up to 1 week. Further dilute in a buffer containing a carrier protein or stabilizer (e.g. 0.1% BSA, 10%FBS, 5%HSA or 5% trehalose solution), protein aliquots should be stored at -20°C or -80°C for 3-6 months. Avoid repeated freeze/thaw cycles.
Bioactivity	Measure by its ability to induce HUVEC cells proliferation. The ED₅₀ for this effect is <5 ng/mL. The specific activity of recombinant human VEGF165 is approximately >1.4 x 10⁶ IU/mg.
Endotoxin	<0.1 EU per 1 μg of the protein by the LAL method.

Synonyms	VPF, Folliculostellate cell-derived growth factor, Glioma-derived endothelial cell mitogen
Summary	Vascular Endothelial Growth Factors 165(VEGF165) is a potent growth and angiogenic cytokine which belongs to the VEGF family, includes VEGF-A, VEGF-B, VEGF-C, VEGF-D, VEGF-E, and PIGF. Human VEGF165 is an abundant glycosylated cytokine composed of two identical 165 amino acid chains. Human VEGF165 plays an important role in embryonic vasculogenesis, angiogenesis and neurogenesis.
