表达区间及表达系统（Source）
Human IL-6 Protein, His Tag (IL6-H5243) is expressed from human 293 cells (HEK293). It contains AA Val 30 - Met 212 (Accession # P05231-1).
Predicted N-terminus: His
Request for sequence蛋白结构（Molecular Characterization）
This protein carries a polyhistidine tag at the N-terminus.
The protein has a calculated MW of 22.7 kDa. The protein migrates as 25-27 kDa and 29-30 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
偶联（Conjugate）
Unconjugated
内毒素（Endotoxin）
Less than 1.0 EU per μg by the LAL method.
纯度（Purity）
90% as determined by SDS-PAGE.
制剂（Formulation）
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.
