蛋白结构（Molecular Characterization）

This protein carries no "tag".

The protein has a calculated MW of 23.2 kDa. The protein migrates as 25 kDa±3 kDa under reducing (R) condition, and 65 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under non-reducing (NR) condition (SDS-PAGE).

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-HPLC.

制剂（Formulation）

Lyophilized from 0.22 μm filtered solution in 20 mM NaAc, pH4.5 with trehalose as protectant.
