Recombinant Human Vascular Endothelial Growth Factor A

Cat. No.: VEGFA-17H
Product Overview: Recombinant human VEGF165produced inE.coliis a 38.2 kDa disulfide-linked homodimeric protein consisting of two 165 amino acid polypeptide chains.
Description: VEGF is a potent growth and angiogenic cytokine. It stimulates proliferation and survival of endothelial cells, and promotes angiogenesis and vascular permeability. Expressed in vascularized tissues, VEGF plays a prominent role in normal and pathological angiogenesis. Substantial evidence implicates VEGF in the induction of tumor metastasis and intra-ocular neovascular syndromes. VEGF signals through the three receptors; fms-like tyrosine kinase (flt-1), KDR gene product (the murine homolog of KDR is the flk-1 gene product) and the flt4 gene product.
Purity: >95% by SDS-PAGE and HPLC analyses.
Formulation: Lyophilized from a 0.2mm filtered concentrated solution in PBS, pH 7.4.
Specific Activity: Fully biologically active when compared to standard. 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 1EU/mg of rHuVEGF165as determined by LAL method.
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.
Storagee: This lyophilized preparation is stable at 2-8°C, but should be kept at -20°C for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8°C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20°C to -70°C. Avoid repeated freeze/thaw cycles.This lyophilized preparation is stable at 2-8°C, but should be kept at -20°C for long term storage, preferably desiccated.
