Recombinant Mouse Il21r protein(Met1-Pro236), hFc-tagged

• Cat.No.: Il21r-448M
• Product Overview: Recombinant Mouse Il21r (AAL82636.1) (Met1-Pro236) was expressed in HEK293 with the Fc region of Human IgG1 at the C-terminus.

Specification

• Source: HEK293
• Species: Mouse
• Tag: Fc
• Protein length: Met1-Pro236
• 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 inhibit mouse IL-21-induced Interferon gamma secretion by human natural killer lymphoma NK-92 cells. The ED50 for this effect is typically 0.2-1.5 μg/mL in the presence of 50 ng/mL of recombinant mouse IL-21.
• Molecular Mass: The recombinant mouse Il21r consists 455 amino acids and predicts a molecular mass of 51.6 kDa.
• Endotoxin: < 1.0 EU per μg protein as determined by the LAL method.
• Purity: > 90 % 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°C before opening to recover the entire contents.
