Origin: It is produced by transient expression in non-transgenic plants. Recombinant Human VEGF 165a is purified by purified standard protein purification methods. This product contains no animal–derived components or impurities. Animal Free product.
Description: Recombinant Human VEGF is a 38.2 kDa homodimeric protein consisting of two 165 amino acid polypeptide chains fused to a 6 His tag at N-terminal. It is a member of the platelet-derived growth factor family. It is a specific mitogen for vascular endothelial cells in vitro and a strong angiogenic factor in vivo. It induces endothelial cell proliferation, promotes cell migration, inhibits apoptosis and induces permeabilization of blood vessels. Expressed in vascularized tissues, VEGF plays a prominent role in normal and pathological angiogenesis. In addition to its action as a mitogen it is a potent vascular permeability factor (VPF) in vivo and is also a chemo attractant for monocytes cells.
Purity: > 95% by SDS-PAGE gel
Endotoxin: < 0.04 EU / μg protein (LAL method)
Formulation: Lyophilized PBS pH 7.5 .Sterile filtered through 0.2 µm filter.
Reconstitution: Always centrifuge the vial before opening. Lyophilized protein should be reconstituted in water following instructions of batch Quality Control Sheet. At higher concentrations solubility may be reduced and, due to the protein nature, dimmers and multimers generated. Optimal concentration should be determined for specific application.
Storage and Stability: This lyophilized preparation is stable at 2-8º C for short term. For longer storage it should be kept at -20ºC. Reconstituted protein should be stored in working aliquots at –20°C. Repeated freezing and thawing is not recommended.
