    Product Description

     

    Vascular endothelial growth factor (VEGF) is a highly specific mitogen for vascular endothelial cells. Five VEGF isoforms are generated as a result of alternative splicing from a single VEGF gene. These isoforms differ in their molecular mass and in biological properties such as their ability to bind to cell-surface heparan-sulfate proteoglycans. The 165-amino acid form of vascular endothelial growth factor (VEGF165) is a mitogen for vascular endothelial cells and a potent angiogenic factor. Human VEGF165 shares 88% aa sequence identity with corresponding regions of mouse and rat, 96% with porcine, 95% with canine, and 93% with feline, equine and bovine VEGF, respectively. Co-expression of NRP1 and (VEGFR-2) KDR on the surface of endothelial cells (EC) enhances VEGF165 binding to KDR and EC chemotaxis in response to VEGF165. Overexpression of NRP1 by prostate tumor cells in vivo results in increased tumor angiogenesis and growth.

    Physical Appearance

    Sterile Filtered White lyophilized (freeze-dried) powder.

    Purity

    > 97 % by SDS-PAGE and HPLC analyses.

    Biological Activity

    The ED50 as determined by a cell proliferation assay using human umbilical vein endothelial cells(HUVEC) is between 1.0-8.0 ng/ml. Fully biologically active when compared to standard.

    Endotoxin

    0.1 EU per 1μg of the protein by the LAL method.

    Formulation

    Lyophilized from a 0.2 μm filtered concentrated solution in PBS, pH 7.4, with 0.02 % Tween-20.

    Reconstitution

    We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1 % BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20 °C. Further dilutions should be made in appropriate buffered solutions.

     

    Shipping and Storage

     

    The products are shipped with ice pack and can be stored at -20 to -80 for 1 year.

    Recommend to aliquot the protein into smaller quantities when first used and avoid repeated freeze-thaw cycles.

     

    Cautions

     

    Avoid repeated freeze-thaw cycles.

    For your safety and health, please wear lab coats and disposable gloves for operation.
