Biological Activity
Determined by the dose-dependent stimulation of the proliferation of human umbilical vein endothelial cells (HUVEC) using a concentration range of 1-6ng/ml corresponding to a Specific Activity of 166,667-1,000,000IU/mg.

Description
Vascular Endothelial Growth Factor Human Recombinant produced in HEK293 cells is a double, glycosylated, polypeptide chain containing 165 amino acids and having a molecular mass of 40 kDa. The VEGF is purified by proprietary chromatographic techniques.

Formulation
The protein was lyophilized from a concentrated (1mg/ml) solution with no additives.

Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.

Protein content
Protein quantitation was carried out by two independent methods
1. UV spectroscopy at 280 nm using the absorbency value of 0.2875 as the extinction coefficient for a 0.1% (1mg/ml) solution. This value is calculated by the PC GENE computer analysis program of protein sequences (IntelliGenetics).

2. Analysis by RP-HPLC, using a calibrated solution of VEGF as a Reference Standard.

Purity
Greater than 95.0% as determined by SDS-PAGE.

Solubility
It is recommended to reconstitute the lyophilized Vascular Endothelial Growth Factor-HEK in sterile 18M?-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.

Source
HEK293 (Human Embryonic Kidney cell line).

Stability
Lyophilized Vascular Endothelial Growth Factor HEK although stable at room temperature for 3 weeks, should be stored desiccated below -18¡ãC. Upon reconstitution VEGF HEK should be stored at 4¡ãC between 2-7 days and for future use below -18¡ãC. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.

Synonyms
Vascular endothelial growth factor A, VEGF-A, Vascular permeability factor, VPF, VEGF, MGC70609.
