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 43.8 kDa. The protein migrates as 50-55 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.

>90% as determined by SEC-MALS.

制剂（Formulation）

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 . Normally trehalose is added as protectant before lyophilization.
