Inquiry Info. # 8065

Please see our recommended alternatives.

    Product Information

    Formulation

    With carrier: Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.2 containing 20 μg BSA per 1 μg hVEGF165. Carrier free: Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.2.

    Storage

    Stable in lyophilized state at -20°C for 1 year after receipt. Sterile stock solutions reconstituted with carrier protein are stable at 4°C for 2 months and at -20°C for 6 months. Avoid repeated freeze-thaw cycles.
    Maintain sterility. Storage at -20°C should be in a manual defrost freezer.

    Product Description

    MW (kDa) 26
    Purity >98% as determined by SDS-PAGE of 6 μg reduced (+) and non-reduced (-) recombinant hVEGF165. All lots are greater than 98% pure.
    Endotoxin Less than 0.01 ng endotoxin/1μg hVEGF165.
    Activity The bioactivity of recombinant hVEGF165 was determined in a cell proliferation assay using HUVEC. The ED50 of each lot is between 1-6 ng/ml.
    Molecular Formula Recombinant hVEGF165 contains no "tags" and has a calculated MW of 19,165. DTT-reduced protein migrates as a 24 kDa polypeptide and the non-reduced cystine-linked homodimer migrates as a 40 kDa protein. The expected amino-terminal APMAE of recombinant hVEGF165 was verified by amino acid sequencing.

    Source / Purification

    Recombinant human VEGF165 (hVEGF165) Ala207-Arg371 (Accession #NP_001020539) was expressed in human 293 cells at Cell Signaling Technology.

    Background

    VEGF165 is the most abundant splice variant of VEGF-A (1,2). VEGF165 is produced by a number of cells including endothelial cells, macrophages and T cells. VEGF165 is involved in angiogenesis, vascular endothelial cell survival, growth, migration and vascular permeability (1). VEGF gene expression is induced by hypoxia, inflammatory cytokines and oncogenes (1,2). VEGF165 binds to heparan sulfate and is retained on the cell surface and in the extracellular matrix (2,3). VEGF165 binds to the receptor tyrosine kinases, VEGFR1 and VEGFR2 (1). VEGF165 is the only splice variant that binds to co-receptors NRP-1 and NRP-2 (1-3) that function to enhance VEGFR2 signaling (1). Binding of VEGF165 to VEGFR1 and VEGFR2 leads to activation of the PI3K/AKT, p38 MAPK, FAK and paxillin (1). VEGF plays a key role in tumor angiogenesis in many cancers (2).
