表达区间及表达系统（Source）	Recombinant Human IL-11 Protein is expressed from HEK293 with His tag at the N-Terminus It contains Pro22-Leu199 [Accession \| P20809-1].
分子量大小（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.
纯度（Purity）	>95% as determined by Bis-Tris PAGE; >95% as determined by HPLC
内毒素（Endotoxin）	Less than 1 EU per μg by the LAL method.
制剂（Formulation）	Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
重构方法（Reconstitution）	Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
存储（Storage）	-20 to -80°C for 24 months as supplied from date of receipt; -80°C for 3 months after reconstitution; 2-8°C for 2-7 days after reconstitution; Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
