Product Introduction
Bioactivity
Chemical Properties
Storage & Solubility Information
| Bioactivity | 1. Immobilized Her2/ERBB2 Protein, Cynomolgus, Recombinant (ECD, hFc Tag) at 2 μg/ml (100 μl/well) can bind Anti-Erbb2 Antibody (Trastuzumab), the EC50 is 15-70 ng/mL.
2. Measured by its ability to block anti-ErbB2 mediated inhibition of BT474 human breast ductal carcinoma cell proliferation. The ED50 for this effect is 0.3-1.8 μg/mL in the presence of 0.6 µg/mL Anti-ErbB2/Her2 Monoclonal Antibody. |
| Description | HER2/ERBB2 Protein, Cynomolgus, Recombinant (hFc) is expressed in HEK293 mammalian cells with hFc tag. The predicted molecular weight is 96.4 kDa. |
| Species | Cynomolgus |
| Expression System | HEK293 Cells |
| Tag | C-hFc |
| Construction | A DNA sequence encoding the cynomolgus ERBB2 (Met1-Thr652) [ Rhesus ERBB2 (XP_001090430.1,Asp121Asn,Leu122Pro); similar to Macaca fascicularis ERBB2 (EHH58073.1)], was expressed with the Fc region of human IgG1 at the C-terminus. Predicted N terminal: Thr 23 |
| Protein Purity | > 85 % as determined by SDS-PAGE. |
| Endotoxin | < 1.0 EU/μg of the protein as determined by the LAL method. |
| Formulation | Lyophilized from a solution filtered through a 0.22 μm filter, containing PBS, pH 7.4. Typically, a mixture containing 5% to 8% trehalose, mannitol, and 0.01% Tween 80 is incorporated as a protective agent before lyophilization. |
| Reconstitution | A Certificate of Analysis (CoA) containing reconstitution instructions is included with the products. Please refer to the CoA for detailed information. |
| Synonyms | erb-b2 receptor tyrosine kinase 2, EGFR2 |
| Research 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.Cancer ImmunotherapyImmune CheckpointImmunotherapyTargeted Therapy |
| Molecular Weight | 96.4 kDa (predicted) |
| Shipping | In general, lyophilized powders are shipped with blue ice, while solutions are shipped with dry ice. |
| Storage | It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots. |
