GMP Recombinant Human IL4 Protein

• Cat.No.: IL4-139HGB
• Product Overview: Recombinant IL4 (P05112-1) (His25-Ser153) was expressed with a N-terminal Met in an animal component free process under cGMP guidelines. The purified protein was biotinylated in vitro.

Specification

• Source: E. coli
• Species: Human
• Predicted N Terminal: Met
• Form: Lyophilized from sterile PBS, pH 7.4, 5 % trehalose, 5 % mannitol and 0.01% Tween80.
• Molecular Mass: The GMP recombinant IL4 consists of 130 amino acids and predicts a molecular mass of 15.1 kDa.
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method.
• Purity: > 93.8 % 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 0.25 mg/ml. Centrifuge the vial at 4°C before opening to recover the entire contents.
• Shipping: In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.
  Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
