来源/表达系统 (Source)
Recombinant Human GDF15 Protein is expressed from E.coli with His tag at the N-Terminus.It contains Ala197-Ile308 [Accession | Q99988-1].
分子量
The protein has a predicted MW of 13.5 kDa. The protein migrates to 15-16 kDa based on Bis-Tris PAGE result.
内毒素 (Endotoxin)
Less than 1 EU per μg by the LAL method.
纯度 (Purity)
> 95% as determined by Bis-Tris PAGE
制剂 (Formulation)
Lyophilized from 0.22 μm filtered solution in 50mM HAc (pH 2.9). Normally 8% trehalose is added as protectant before lyophilization.
重构方法 (Reconstitution)
Dissolve the lyophilized protein in 50 mM HAc (pH 2.9). Please refer to the Certificate of Analysis for detailed instructions.
存储 (Storage)
-20 to -80°C for 12 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.
