  • Specifications
    • Species of Origin

      Human

      Expression System

      Escherichia coli

    • Affinity Tag

      His Tag (C-term)

      Storage Buffer

      Lyophilized from a 0.2 µm filtered solution of PBS, pH 8.0.

    • Purity

      >95% as determined by SDS-PAGE analysis.

      Molecular weight

      The protein has a calculated MW of 15.00 kDa.
      The protein migrates as 15 kDa under reducing condition (SDS-PAGE analysis).

    • Activity

      Measure by its ability to induce proliferation in HUVEC cells. The ED₅₀ for this effect is <2.5 ng/mL.

      Endotoxin Level

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

    • Form

      Lyophilized

  • Background
    • Background

      Vascular Endothelial Growth Factors 121(VEGF121) is one of five VEGF splice variants of 121, 145, 165, 183, 189, and 206 amino acids (aa) in length. VEGF121 is the only VEGF which lacks heparin-binding activity and freely diffusible. VEGF binds the type I transmembrane receptor tyrosine kinases VEGF R1 (also called Flt-1) and VEGF R2 (Flk-1 /KDR) on endothelial cells to activate signal transduction and regulate both physiological and pathological angiogenesis.

      Synonyms

      Vascular endothelial Growth Factors A, VEGF-A, Vascular permeability factor, VPF

    • Uniprot ID

      #PDB: 3V2A_A

      Sequence Note

      Ala1-Arg121

  • Instruction
    • 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°C or lower for long term storage.

    • Stability & Storage

      This product is stable after storage at:

      • -20°C for 12 months in lyophilized state from date of receipt.
      • -20°C or -80°C for 1 month under sterile conditions after reconstitution.

      Avoid repeated freeze/thaw cycles.
