Recombinant Human IL21R protein, His-tagged

• Cat.No.: IL21R-4795H
• Product Overview: Recombinant Human IL21R protein(Q9HBE5)(Cys20-Glu232), fused with C-terminal His tag, was expressed in HEK293.

Specification

• Species: Human
• Source: C-His
• Protein Length: Cys20-Glu232
• Tag: C-His
• Form: Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
• Bio-activity: Immobilized Human IL-21 at 2μg/ml (100μl/well) on the plate. Dose response curve for Human IL-21R, His Tag with the EC50 of 34.2ng/ml determined by ELISA.
• Molecular Mass: The protein has a predicted MW of 25.65 kDa. Due to glycosylation, the protein migrates to 43-50 kDa based on Tris-Bis PAGE result.
• Endotoxin: Less than 1EU per μg by the LAL method.
• Purity: > 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC.
• Storage: Reconstituted protein stable at -80°C for 12 months, 4°C for 1 week. Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
• Reconstitution: Centrifuge tubes before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
