| Molecular Weight | The recombinant rat ErbB2/Fc is a disulfide-linked homodimer. The reduced monomer comprises 638 amino acids and predicts a molecular mass of 70.6 kDa. The apparent molecular mass of the rat ErbB2 is approximately 95-105 kDa in SDS-PAGE under reducing conditions due to glycosylation. |
| predicted N | Thr 26 |
| SDS-PAGE |  |
| Purity | > 92 % as determined by SDS-PAGE |
| Protein Construction | A DNA sequence encoding the rat ErbB2 (AAH61863.1) extracellular domain (Met 4-Thr 656) was expressed and purified, with seven additional amino acids (ALEVLFQ) at the C-terminus. |

| Research Area | Cardiovascular |Angiogenesis |Growth Factor & Receptor |Receptor Tyrosine Kinase (RTK) |
| Formulation | Lyophilized from sterile PBS, pH 7.4 1. Normally 5 % - 8 % trehalose and mannitol are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA. |
| Background | 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. |
