Recombinant Mouse IL18 protein(Asn36-Ser192)

• Cat.No.: IL18-2366M
• Product Overview: Recombinant Mouse IL18 (P70380-1) (Asn36-Ser192) was expressed and purified in E. coli.

Specification

• Species: Mouse
• Source: E.coli
• Tag: Non
• Protein Length: Asn36-Ser192
• Form: Lyophilized from sterile PBS, pH 7.4. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
• Bio-activity: Measured by its ability to induce IFN-γ secretion by KG-1 human myelomonocyte. The ED50 for this effect is typically 0.1-0.8 μg/mL.
• Molecular Mass: The recombinant mouse IL18 consists of 158 amino acids and predicts a molecular mass of 18.2 KDa. It migrates as an approximately 19 KDa band 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.
