蛋白结构（Molecular Characterization）

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

The protein has a calculated MW of 28.7 kDa. The protein migrates as 32-35 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 Tris, Glycine and NaCl,pH7.5. Normally trehalose is added as protectant before lyophilization.
