Product Description

Cat

IMP-606

Official Symbol

ERBB2

Product Overview

Recombinant Human ERBB2 protein(NP_001005862.1 )(Thr 23-Thr 652), fused to C-His Tag, was expressed in HEK293.

Expression System

HEK293

Species

Human

Tag

C-His Tag

Form

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

Molecular Mass

The protein has a calculated MW of 71.3 kDa. The protein migrates as 80-100 KDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

Protein length

Thr 23-Thr 652

Endotoxin

Less than 1.0 EU per μg by the LAL method.

Purity

>95% as determined by SDS-PAGE.

Storage

For long term storage, the product should be stored at lyophilized state at -20°C or lower.
Please avoid repeated freeze-thaw cycles.
This product is stable after storage at:
-20°C to -70°C for 12 months in lyophilized state;
-70°C for 3 months under sterile conditions after reconstitution.

Reconstitution

It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents.

SDS-PAGE
