Active Recombinant Human IL1R2 protein, His-tagged

• Cat.No.: IL1R2-2200H
• Product Overview: Recombinant Human IL1R2 (Met 1-Glu 343) protein was fused to His-tag at C-terminus and expressed in human 293 cells (HEK293).

Specification

• Source: HEK293
• Species: Human
• Tag: His
• 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.
• Bio-activity: Measured by its ability to inhibit Interferon gamma secretion by human natural killer lymphoma NK-92 cells in the presence of 500pg/mL IL1b.
  The EC50 for this effect is typically 20-80ng/mL.
• Molecular Mass: The recombinant human IL1R2 consists of 341 amino acids and has a predicted molecular mass of 39.2 kDa. As a result of glycosylation, the rh IL1R2 migrates as an approximately 50-55 kDa band in SDS-PAGE under reducing conditions.
• Protein Length: Met 1-Glu 343
• Endotoxin: < 1.0 EU per μg protein as determined by the LAL method.
• Purity: > 95 % as determined by SDS-PAGE. > 90 % as determined by SEC-HPLC.
• 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.
