Purity
> 95 % as determined by SDS-PAGE.
Endotoxin
< 1.0="" eu="" per="" μg="" protein="" as="" determined="" by="" the="" lal="">
Activity
1.Measured by its binding ability in a functional ELISA.2.Immobilizedhuman ErbB2 (Cat:10004-HCCH) at 10μg/mL (100μL/well) can bind herceptin ,the EC50 of herceptinis 7-90ng/mL.3.Measured by its ability to block anti-ErbB2 mediated inhibition of BT474 human breast ductal carcinoma cell proliferation. The ED50 for this effect is 0.4-2.4μg/mL in the presence of 0.6 µg/mL Anti-ErbB2/Her2 Monoclonal Antibody.
Protein Construction
A DNA sequence encoding the human ERBB2 (NP_004439.2) (Met1-Thr652) was expressed with five amino acids (DDDDK) at the C-terminus.
Accession#
NP_004439.2
Expressed Host
HEK293 Cells
Species
Human
Predicted N Terminal
Thr 23
Molecule Mass
The recombinant human ERBB2 consists 636 amino acids and predicts a molecular mass of 70 kDa. As a result of glycosylation, human ErbB2 migrates as an approximately 100-110 kDa protein in SDS-PAGE under reducing conditions.
Formulation
Lyophilized from sterile PBS, pH 7.4.Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
Please refer to the specific buffer information in the hard copy of CoA.
Shipping
In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
Stability & Storage
Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
Reconstitution
A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.

Her2/ERBB2 Background Information
Human epidermal growth factor receptor 2 (HER2), also known as ErbB2, NEU, and CD340, is a type I membrane glycoprotein and belongs to the epidermal growth factor (EGF) receptor family. HER2 protein cannot bind growth factors due to the lacking of ligand binding domain of its own and autoinhibited constitutively. However, HER2 forms a heterodimer with other ligand-bound EGF receptor family members, therefore stabilizes ligand binding and enhances kinase-mediated activation of downstream molecules. HER2 plays a key role in development, cell proliferation and differentiation. HER2 gene has been reported to associate with malignancy and a poor prognosis in numerous carcinomas, including breast, prostate, ovarian, lung cancers and so on.
