Our experienced scientists design, develop, and optimize assays to verify the identity of your sequences and provide you with:


  • Chromatogram file (.ab1)
  • Analysis report, including identification of mutations or discrepancies
  • Sequence file (.seq)
  • Consensus sequence of results (.seq)
  • Analysis report, including identification of mutations or discrepancies

  • Applications of Confirmatory Sequencing

    Sanger-based confirmatory sequencing of both DNA and RNA/cDNA templates has been utilized to support the following applications:

    CRISPR Confirmation

    Confirmation of target CRISPR integrations (& identification of off-target effects)

    Next Generation Sequencing Confirmation

    Confirmation of mutations identified by NGS screens

    Antibody Sequencing Confirmation

    Confirmation of heavy-chain/light-chain sequences for monoclonal antibodies

    Cell Line/Cell Bank Confirmation

    Genotyping & confirmation of engineered cell lines (cell line ID/stability)

    Gene Synthesis Product Confirmation

    Confirmation of clones and gene editing products    

    Transfection Verification

    Confirmation of genomic integrations in cell lines & viral vectors (lentivirus or AAV)
