Active Recombinant Human TGFA protein

• Cat.No.: TGFa-149H
• Product Overview: Recombinant Human TGFA protein(P01135-1)(Val40-Ala89) was expressed in E. coli.

Specification

• Species: Human
• Source: E.coli
• Tag: Non
• Protein Length: Val40-Ala89
• Form: Lyophilized from sterile 50 mM Tris, 100 mM NaCl, pH 8.0.Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
• Bio-activity: 1.Measured by its binding ability in a functional ELISA. Immobilized Human TGF-alpha at 2 μg/ml (100 μl/well) can bind Human EGFR hFc, the EC50 of Human EGFR hFc is 80-500 ng/mL.2. Measured in a cell proliferation assay using Balb/c 3T3 mouse embryonic fibroblast cells. The ED50 for this effect is 0.5-2.5 ng/mL.
• Molecular Mass: The recombinant human TGFa consists of 50 amino acids and has a predicted molecular mass of 5.6 kDa. The apparent molecular mass of it is approximately 13 kDa in SDS-PAGE under reducing conditions.
• Purity: > 90 % as determined by SDS-PAGE
• Storage: Samples are stable for up to twelve months from date of receipt at -20°C to -80°C
  Store it under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
• Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents.
