• Cat.No.: GDF15-4755H
• Product Overview: Recombinant Human GDF15 protein(Q99988-1)(Ala197-Ile308), fused with N-terminal His tag, was expressed in E.coli.

Specification

• Species: Human
• Source: E.coli
• Tag: His
• Protein Length: 197-308 aa
• Form: Lyophilized from 0.22 μm filtered solution in 50mM HAc (pH 2.9). Normally 8% trehalose is added as protectant before lyophilization.
• Bio-activity: Immobilized Human GDF15, His Tag at 0.5 μg/ml (100 μl/well) on the plate. Dose response curve for Human GFRAL, hFc Tag with the EC50 of 13.1 ng/ml determined by ELISA.
• Molecular Mass: The protein has a predicted MW of 13.5 kDa.The protein migrates to 15-16 kDa based on Bis-Tris PAGE result.
• Endotoxin: Less than 0.01 EU per μg by the LAL method.
• Purity: > 95% as determined by Bis-Tris PAGE
• Storage: Store at -20 to -80°C for 24 months as supplied from date of receipt. -80°C for 3 months after reconstitution. Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
• Reconstitution: Dissolve the lyophilized protein in distilled water.
