Species of Origin
His Tag (C-term)
Lyophilized from a 0.2 µm filtered solution of PBS, pH 8.0.
>98% as determined by SDS-PAGE analysis.
The protein has a calculated MW of 6.49 kDa.
The protein migrates as 7 kDa under reducing condition (SDS-PAGE analysis).
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.
<0.1 EU per 1 μg of the protein by the LAL method.
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.
EGF-like TGF, ETGF, TGF type 1, Protransforming Growth Factors alpha
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.
The product is shipped with polar packs. Upon receipt, store it immediately at -20°C or lower for long term storage.
