Active Recombinant Human VEGFA Protein (Ala27-Arg191), C-His tagged, Animal-free, Carrier-free

• Cat.No.: VEGFA-292H
• Product Overview: Recombinant Human VEGFA Protein (Ala27-Arg191) with C-His tag was expressed in E. coli and Animal-free as well as Carrier-free.

Specification

• Species: Human
• Source: E.coli
• Tag: His
• Protein Length: Ala27-Arg191
• Description: Vascular Endothelial Growth Factors 165(VEGF165) is a potent growth and angiogenic cytokine which belongs to the VEGF family, includes VEGF-A, VEGF-B, VEGF-C, VEGF-D, VEGF-E, and PIGF. Human VEGF165 is an abundant glycosylated cytokine composed of two identical 165 amino acid chains. Human VEGF165 plays an important role in embryonic vasculogenesis, angiogenesis and neurogenesis.
• Form: Lyophilized
• Bio-activity: Measure by its ability to induce HUVEC cells proliferation. The ED50 for this effect is < 5 ng/mL. The specific activity of recombinant human VEGF165 is approximately >1.4 × 10⁶ IU/mg.
• Molecular Mass: The protein has a calculated MW of 20.11 kDa.
  The protein migrates as 21 kDa under reducing condition (SDS-PAGE analysis).
• Endotoxin: < 0.1 EU/μg of the protein by the LAL method.
• Purity: >98% as determined by SDS-PAGE analysis.
• Storage: This product is stable after storage at:
  -20 centigrade for 12 months in lyophilized state from date of receipt.
  -20 or -80 centigrade for 1 month under sterile conditions after reconstitution.
  Avoid repeated freeze/thaw cycles.
• Storage Buffer: Lyophilized from a 0.2 μm filtered solution of PBS, pH 8.0.
• Reconstitution: It is recommended to reconstitute the lyophilized protein in sterile H2O to a concentration not less than 200 μg/mL and incubate the stock solution for at least 20 min to ensure sufficient re-dissolved.
• Shipping: The product is shipped with polar packs. Upon receipt, store it immediately at -20 centigrade or lower for long term storage.
