Recombinant Human VEGF-A/VEGF121(K321N) Protein (RP00017)

Overview

Product name	Recombinant Human VEGF-A/VEGF121(K321N) Protein
Catalog No.	RP00017
Description	Recombinant Human VEGF-A/VEGF121(K321N) Protein is produced by E. coli expression system. The target protein is expressed with sequence (Ala207-Arg327 (Lys321Asn)) of human VEGF121 (Accession #NP_001020541.2).
Bio-Activity	1.Measured by its binding ability in a functional ELISA. Immobilized Human VEGF121 at 2 μg/mL (100 μL/well) can bind Human KDR with a linear range of 0.2-10 ng/mL. 2.Measured in a cell proliferation assay using human umbilical vein endothelial cells (HUVEC). The ED₅₀ for this effect is typically 0.017-0.068 ng/mL, corresponding to a specific activity of 1.47 ×10⁷-5.88 ×10⁷units/mg.
Purity	> 97% by SDS-PAGE.
Endotoxin	< 1.0 EU/μg of the protein by LAL method.
Formulation	Lyophilized from a 0.22 μm filtered solution of 20mM Tris, 100mM NaCl, pH 8.0.Contact us for customized product form or formulation.
Species	Human
Calculated MW	14.06 kDa

This protein is a member of the PDGF/VEGF growth factor family. It encodes a heparin-binding protein, which exists as a disulfide-linked homodimer. This growth factor induces proliferation and migration of vascular endothelial cells, and is essential for both physiological and pathological angiogenesis. Disruption of this gene in mice resulted in abnormal embryonic blood vessel formation. This protein is upregulated in many known tumors and its expression is correlated with tumor stage and progression. Elevated levels of this protein are found in patients with POEMS syndrome, also known as Crow-Fukase syndrome.

Usage guide

Storage	Store at -20℃.Store the lyophilized protein at -20℃ to -80 ℃ up to 1 year from the date of receipt. After reconstitution, the protein solution is stable at -20℃ for 3 months, at 2-8℃ for up to 1 week.
Reconstitution	Centrifuge the vial before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid vortex or vigorously pipetting the protein. For long term storage, it is recommended to add a carrier protein or stablizer (e.g. 0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose), and aliquot the reconstituted protein solution to minimize free-thaw cycles.
