Recombinant Human HER2 /ErbB2 (23-450) Protein, C-Fc Tag

  • Synonym
    ERBB2,CD340,HER-2/neu,HER2,MLN19,NEU,NGL,TKR1
  • Source
    Human Her2 (23-450), Fc Tag (HE2-H525x) is expressed from human 293 cells (HEK293). It contains AA Thr 23 - Ile 450 (Accession # AAA75493).
    Predicted N-terminus: Thr 23
  • Molecular Characterization
    Her2(Thr 23 - Ile 450) AAA75493

    rh HER2 / ErbB2 (23-450) Fc Chimera is fused with a human IgG1 Fc tag at the C-terminus, and has a calculated MW of 74.5 kDa. The predicted N-terminus is Thr 23. The reducing (R) protein migrates as 95-100 kDa in SDS-PAGE due to glycosylation.

    rh HER2 / ErbB2 (23-450) Fc Chimera does not contain Herceptin mAb binding domain.

  • Endotoxin
    Less than 1.0 EU per μg by the LAL method.
  • Purity

    >95% as determined by SDS-PAGE.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 100 mM Glycine, pH7.5. Normally trehalose is added as protectant before lyophilization.

    Contact us for customized product form or formulation.

  • Reconstitution

    Please see Certificate of Analysis for specific instructions.

    For best performance, we strongly recommend you to follow the reconstitution protocol provided in the CoA.

  • Storage

    For long term storage, the product should be stored at lyophilized state at -20°C or lower.

    Please avoid repeated freeze-thaw cycles.

    No activity loss is observed after storage at:

    1. 4-8°C for 12 months in lyophilized state;
    2. -70°C for 3 months under sterile conditions after reconstitution.
SDS-PAGE
Human Her2 (23-450), Fc Tag (Cat. No. HE2-H525x) SDS-PAGE gel

Human Her2 (23-450), Fc Tag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 95%.
