表达区间及表达系统（Source）

Human PAI-1 Protein is expressed from HEK293 with His tag at the C-terminal. It contains Val24-Pro402.[Accession | P05121-1]

分子量大小（Molecular Weight）

The protein has a predicted MW of 43.86 kDa. Due to glycosylation, the protein migrates to 45-55 kDa based on Tris-Bis PAGE result.

内毒素（Endotoxin）

Less than 1EU per μg by the LAL method.

纯度（Purity）

> 95% as determined by Tris-Bis PAGE and HPLC

制剂（Formulation）

Lyophilized from 0.22 μm filtered solution in 50mM NaAC, 0.1M NaCl, 100mM L-arginine (pH 5.5). Normally 8% trehalose is added as protectant before lyophilization.
