ERBB2,CD340,HER-2/neu,HER2,MLN19,NEU,NGL,TKR1

表达区间及表达系统（Source）

Human Her2, Strep Tag (HE2-H5287) is expressed from human 293 cells (HEK293). It contains AA Thr 23 - Thr 652 (Accession # AAA75493).

Predicted N-terminus: Thr 23

蛋白结构（Molecular Characterization）

This protein carries a twin strep tag at the C-terminus.

The protein has a calculated MW of 72.4 kDa. The protein migrates as 90-115 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 PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.
