Active Recombinant Mouse Il21 protein

• Cat.No.: Il21-844M
• Product Overview: Recombinant Mouse Il21 protein(Q9ES17)(Pro25-Ser146) was expressed in E. coli.

Specification

• Source: E. coli
• Species: Mouse
• Tag: N/A
• Form: Lyophilized from sterile PBS, pH 7.5Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hard copy of CoA.
• Bio-activity: Measured by its ability to induce Interferon gamma secretion by human natural killer lymphoma NK-92 cells.The ED50 for this effect is typically 4-20 ng/ml.
• Molecular Mass: The recombinant mouse IL21 consists of 123 amino acids and has a calculated molecular mass of 14.3KDa. It migrates as a 15 kDa band in SDS-PAGE under reducing conditions.
• Protein Length: Pro25-Ser146
• Purity: > 97 % 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.
