Source / expression
Recombinant Human IL-11 Protein is expressed from HEK293 with His tag at the N-Terminus It contains Pro22-Leu199 [Accession | P20809-1].
Molecular weight
The protein has a predicted MW of 20.24 kDa. Due to glycosylation, the protein migrates to 21-25 kDa based on Bis-Tris PAGE result.
Endotoxin
Less than 1 EU per μg by the LAL method.
Purity
> 95% as determined by Bis-Tris PAGE
Formulation
Lyophilized from 0.22 μm filtered solution in 20mM Citric acid (pH 3.0). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution
Dissolve the lyophilized protein in 20mM Citric acid (pH 3.0). Please refer to the Certificate of Analysis for detailed instructions.
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.
