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

    • Purity

      >98% as determined by SDS-PAGE analysis.

      Molecular weight

      The protein has a calculated MW of 6.49 kDa.
      The protein migrates as 7 kDa under reducing condition (SDS-PAGE analysis).

    • Activity

      Measure by its ability to induce 3T3 cells proliferation. The ED₅₀ for this effect is <0.2 ng/mL. The specific activity of recombinant human TGF alpha is > 5 x 10⁶ IU/mg.

      Endotoxin level

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

    • Form


  • Background
    • Background

      Transforming Growth Factors alpha (TGF-α) is a 5.68 kDa member of the epidermal Growth Factors with 51 amino acid residues. TGF-α is mainly expressed from brain, skin, epithelial cell (pancreatic endocrine cells, urothelial cells, oligodendrocyte precursor cells, etc.). TGF-α is a regulator of cell proliferation and differentiation via bind to the EGFR and to act synergistically with TGF β. TGF-α also associates with myriad forms of cancer.
