Recombinant Cynomolgus IL13 protein, His-tagged

• Cat.No.: IL13-1496C
• Product Overview: Recombinant Cynomolgus IL13 protein(Q0PW92)(Ser19-Asn132), fused with N-terminal His tag, was expressed in HEK293.

Specification

• Species: Cynomolgus
• Source: N-His
• Protein Length: Ser19-Asn132
• Tag: N-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 Cynomolgus IL-13, His Tag at 5μg/ml (100μl/well) on the plate. Dose response curve for Human IL-13Ra2, hFc Tag with the EC50 of 1.72μg/ml determined by ELISA.
• Molecular Mass: The protein has a predicted MW of 13.59 kDa. Due to glycosylation, the protein migrates to 30-45 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.
