Human VEGF Protein

SKU: orb169544

Description

Recombinant of Human VEGF protein

Images & Validation

−

Application Notes

Protein content: VEGF 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:(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE.

Storage & Handling

−

Storage	Stability: Lyophilized VEGF although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution VEGF should be stored at 4°C between 2-7 days and for future use below -18°C.For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles
Form/Appearance	Sterile Filtered White lyophilized (freeze-dried) powder.
Buffer/Preservatives	The VEGF protein was lyophilized from a concentrated (1mg/ml) solution with no additives.
Expiration Date	6 months from date of receipt.
Disclaimer	For research use only

Alternative Names

−

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