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. The purified protein was biotinylated in vitro.
Reconstitution
It is recommended that the sterile water (400ul) be added to the vial to prepare a stock solution of 0.25mg/mL. Concentration is measured by UV.
Biological Activity
1. Immobilized Anti-Erbb2 Antibody at 2 ug/ml (100 ul/well) can bind Recombinant Human HER2 / ErbB2 Protein (ECD), Biotinylated (Cat: MBS8119936), the EC50 is 0.8-2.6 ng/mL.
2. Using the Octet RED System, the affinity constant (Kd) of Her2 / ERBB2 Protein, Human, Recombinant, Biotinylated (Cat: MBS8119936) bound to Pertuzumab was 0.1 nM.
2. Using the Octet RED System, the affinity constant (Kd) of Her2 / ERBB2 Protein, Human, Recombinant, Biotinylated (Cat: MBS8119936) bound to Pertuzumab was 0.1 nM.
Preparation and Storage
Samples are stable for twelve months from date of receipt at -20°C to -80°C. Store it under sterile conditions at -20°C to -80°C upon receiving. Recommend to aliquot the protein into smaller quantities for optimal storage.
Related Product Information for ERBB2 active protein
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.

Product Notes
The ERBB2 erbb2 (Catalog #AAA257810) is an Active Protein produced from HEK293 Cells and is intended for research purposes only. The product is available for immediate purchase. The amino acid sequence is listed below: Met1-Thr65 2. It is sometimes possible for the material contained within the vial of "Her2/ERBB2, Active Protein" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
