蛋白结构（Molecular Characterization）

This protein carries a polyhistidine tag at the N-terminus, followed by an Avi tag (Avitag™).

The protein has a calculated MW of 15.2 kDa. The protein migrates as 18 kDa and 19-25 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

标记（Biotinylation）

Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.

蛋白标记度（Biotin:Protein Ratio)

Passed as determined by the HABA assay / binding ELISA.

内毒素（Endotoxin）

Less than 1.0 EU per μg by the LAL method.

纯度（Purity）

>95% as determined by SDS-PAGE.

>95% 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.
