Recombinant Human IL18, GST tagged

• Cat.No.: IL18-574H
• Product Overview: Recombinant Human IL18 (Q14116) (Met1-Asp193), fused with the GST tag at the N-terminus, was produced in E. coli.

Specification

• Species: Human
• Source: E.coli
• Tag: His
• ProteinLength: 1-193 a.a.
• Predicted N Terminal: Met
• Form: Lyophilized from sterile PBS, pH 7.5Normally 5 % - 8 % trehalose and mannitol are added as protectants before lyophilization.
• Molecular Mass: The recombinant human IL18/GST chimera consists of 419 amino acids and has a predicted molecular mass of 48.6 kDa. It migrates as an approxiamtely 45 kDa band in SDS-PAGE under reducing conditions.
• Endotoxin: < 1.0 eu per μg of the protein as determined by the LAL method.
• Purity: >85 % as determined by SDS-PAGE
• Stability: Samples are stable for up to twelve months from date of receipt at -70oC.
• Storage: Store it under sterile conditions at -20oC~-70oC. 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. Centrifuge the vial at 4℃ before opening to recover the entire contents.
