Sanger Sequencing With Ampliseq Primers and Libraries

Formalin-fixed paraffin-embedded (FFPE) tissue is a standard sample type in histology and pathology laboratories; however, the fixation process often damages DNA, resulting in a limited amount of starting material for molecular genetic analysis. In order to extract maximal information from minimal sample amounts, we developed a workflow that enables robust genotyping results from less than 1 ng of FFPE DNA. Utilizing Ion AmpliSeq technology with Sanger sequencing, the workflow offers an ideal solution for routine labs working with a limited number of samples/targets, as well as high-throughput labs that need an orthogonal method for confirming minor alleles.

Researchers who need a fast and economical solution for confirmation of uncertain NGS results can rely on the robustness and sensitivity of PCR coupled with Sanger sequencing.

  • Sanger sequencing results can be obtained using Ion AmpliSeq library primer sequences or from existing Ion AmpliSeq library pools
  • Robust genotyping results using both Ion AmpliSeq next-generation sequencing (NGS) and confirmatory sequencing can be generated from less than 1 ng of FFPE DNA
  • Previously sequenced NGS libraries can be used as a direct input for confirmatory Sanger sequencing

Application note: Sanger sequencing using Ion AmpliSeq primers and libraries

This study demonstrates how Ion AmpliSeq panels analyzed by Sanger sequencing can be used to verify the presence of unusual or low-frequency alleles in a sample.
