蛋白结构（Molecular Characterization）

This protein carries a polyhistidine tag at the C-terminus.

The protein has a calculated MW of 8.6 kDa. The protein migrates as 13 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

内毒素（Endotoxin）

Less than 1.0 EU per μg by the LAL method.

纯度（Purity）

>95% as determined by SDS-PAGE.

制剂（Formulation）

Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 100 mM NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.
