Active Recombinant Human ErbB2 protein, hFc-tagged, Biotinylated

• Cat.No.: ErbB2-2150H
• Product Overview: Biotinylated Recombinant Human ErbB2 protein(NP_004439.2)(Met1-Thr652), fused with hFc tag, was expressed in HEK293.

Specification

• Source: HEK293
• Species: Human
• Tag: hFc
• Form: Lyophilized from sterile PBS, pH 7.4Please 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.
• Bio-activity: Immobilized Her2/ERBB2 Protein, Human, Recombinant (hFc Tag), Biotinylated at 2 μg/ml (100 μl/well) can bind Anti-Erbb2 Antibody (Trastuzumab), the EC50 is 20-110 ng/mL.
• Molecular Mass: The recombinant human ErbB2/Fc chimera is a disulfide-linked homodimeric protein generated by proteolytic removal of the signal peptide. The monomer consists of 868 amino acids and predicts a molecular mass of 96.1 kDa.
• Protein Length: Met1-Thr652
• Endotoxin: < 1.0 EU per μg protein as determined by the LAL method.
• Purity: > 90 % as determined by SDS-PAGE
• Storage: Samples are stable for up to twelve months from date of receipt at -20°C to -80°C
  Store it under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
• 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.
