表达区间及表达系统（Source）
Human IL-11, Fc Tag (IL1-H5269) is expressed from human 293 cells (HEK293). It contains AA Pro 22 - Leu 199 (Accession # P20809-1).
Predicted N-terminus: Pro
Request for sequence蛋白结构（Molecular Characterization）
This protein carries a human IgG1 Fc tag at the N-terminus.
The protein has a calculated MW of 45.6 kDa. The protein migrates as 47-55 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
内毒素（Endotoxin）
Less than 0.01 EU per μg by the LAL method / rFC method.
纯度（Purity）
>95% as determined by SDS-PAGE.
>95% as determined by SEC-MALS.
制剂（Formulation）
Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 100 mM Glycine, 25 mM Arginine, 150 mM NaCl, pH7.5 with trehalose as protectant.
