Recombinant Human Vascular Endothelial Growth Factor (VEGF)

Certificate of Analysis and Data Sheet

Source:

E.Coli

Catalog No.

CYT-241

	Background:
	Vascular endothelial growth factor-A was originally isolated from tumor cells and referred to as Tumor Angiogenesis Factor or Vascular Permeability Factor. Although expressed at high levels in certain tumor-derived cells it is produced by a wide variety of cell types. In addition to stimulating vascular growth and vascular permeability it may play a role in stimulating Vasolidation via nitric oxide-dependent pathways. Alternative splicing of the mRNA for VEGF-A results in several isoforms of the protein being produced. Rat and bovine VEGF are one amino acid shorter than the human factor, and the bovine and human sequences show a homology of 95 percent. In contrast to other factors mitogenic for endothelial cells such as FGF-1 , FGF-2 and PDGF, VEGF is synthesized as a precursor containing a typical hydrophobic secretory signal sequence of 26 amino acids. Glycosylation is not required for efficient secretion of VEGF.
	Description :
	Recombinant Human VEGF produced in E.Coli is a double, non-glycosylated, polypeptide chain containing 165 amino acids and having a molecular mass of 38231 Dalton. Recombinant VEGF is purified by proprietary techniques.
	Physical Appearance:
	Sterile Filtered White lyophilized (freeze-dried) powder.
	Formulation:
	Recombinant VEGF was lyophilized from a concentrated (1mg/ml) solution with no additives.
	Solubility:
	It is recommended to reconstitute the lyophilized VEGF in sterile 18M-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
	Stability:
	Lyophilized VEGF although stable at room temperature for 3 weeks, should be stored desiccated below -18 C. Upon reconstitution rHuVEGF 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.
	Purity:
	Greater than 98.0% as determined by: (a) Analysis by RP-HPLC. (b) Anion-exchange FPLC. (c) Analysis by reducing and non-reducing SDS-PAGE Silver Stained gel.
	Amino acid sequence:
	The sequence of the first five N-terminal amino acids was determined and was found to be Ala-Pro-Met-Ala-Glu.
	Dimers and aggregates:
	Less than 1% as determined by silver-stained SDS-PAGE gel analysis.
	Biological Activity:
	The biological activity is determined by the dose-dependent stimulation of the proliferation of human umbilical vein endothelial cells (HUVEC) using a concentration range of 1.0-8.0 ng/ml.
	Endotoxin:
	Less than 0.1 ng/µg (IEU/µg) of VEGF.
	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.
	Usage:
	Prospec's products are furnished for LABORATORY RESEARCH USE ONLY. The product may not be used as drugs, agricultural or pesticidal products, food additives or household chemicals.

	Gene:
	Name:VEGF Synonyms:VEGFA
	Protein synonyms/aliases:
	Vascular endothelial growth factor A precursor (VEGF-A) (Vascularpermeability factor) (VPF).
	Protein Family:
	Belongs to the PDGF/VEGF growth factor family.
