Specification

• Species: Cynomolgus
• Source: N-His
• Protein Length: Arg193-Val308
• Tag: N-His
• Form: Lyophilized from 0.22μm filtered solution in 50mM HAc (pH 2.9). Normally 8% trehalose is added as protectant before lyophilization.
• Bio-activity: Immobilized Cynomolgus GDF15, His Tag at 2μg/ml (100μl/well) on the plate. Dose response curve for Biotinylated Cynomolgus GFRAL, His Tag with the EC50 of 101.8ng/ml determined by ELISA.
• Molecular Mass: The protein has a predicted MW of 14.15 kDa. The protein migrates to 15-18 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.
• 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 50mM HAc (pH 2.9).
