Recombinant Rhesus IL18, His tagged

• Cat.No.: IL18-385R
• Product Overview: Recombinant Rhesus IL18 (Ala 2-Asp 193), fused with an N-terminal polyhistidine tag, was produced in E. coli.

Specification

• Species: Rhesus macaque
• Source: E.coli
• Tag: His
• Protein Length: Ala 2-Asp 193
• Form: Lyophilized from sterile 50 mM Tris, pH 8.0.
  Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
• Molecular Mass: The recombinant rhesus IL18 consists of 203 amino acids and has a calculated molecular mass of 23.7 kDa.
• Purity: > 92 % 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℃ before opening to recover the entire contents.
