Human Her2 / ErbB2 Protein, Tag Free

  • Synonym
    ERBB2,CD340,HER-2/neu,HER2,MLN19,NEU,NGL,TKR1
  • Source
    Human Her2, Tag Free (HE2-H5212) is expressed from human 293 cells (HEK293). It contains AA Thr 23 - Thr 652 (Accession # P04626-1).
    Predicted N-terminus: Thr 23
  • Molecular Characterization
    Online(Thr 23 - Thr 652) P04626-1

    This protein carries no "tag".

    The protein has a calculated MW of 112.8 kDa. The protein migrates as 90-100 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • 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 PBS, pH7.4. 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 was 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.
