DNA and RNA sequencing gives clinicians and researchers detailed information about differences and changes in an individual's genetic makeup, helping them better understand the role that genetics plays in diseases and treatments.

Mayo Clinic's Genome Analysis Core produces a broad spectrum of DNA and RNA sequencing, including Sanger sequencing and both short-read (Illumina) and long-read (Pacific Biosciences) next-generation (deep) sequencing. This service also provides consultations and training in molecular biology techniques.

Next-generation sequencing

Next-generation sequencing is the process of sequencing DNA or RNA by producing millions of sequence reads in a massively parallel manner. Also known as deep sequencing, next-generation sequencing allows for the sequencing of the entire genome, exome or transcriptome. This makes it possible to identify complex genetic differences that may cause disease or help diagnose and treat disease. The Genome Analysis Core offers a full range of services and applications for next-generation sequencing, including:

  • Whole-genome sequencing
  • Whole-exome and custom capture
  • Mate Pair sequencing
  • ChIP-Seq
  • Reduce Representation BiSulfite sequencing
  • Whole-transcriptome sequencing (mRNA-seq)
  • Total RNA sequencing
  • MicroRNA sequencing (miRNA-seq)

Because next-generation DNA sequencing is a complex process involving various types of library preparations, sequencing and data analysis, a meeting with the sequencing core and data analysis staff is required to properly plan a new research project.

Sanger sequencing

The Genome Analysis Core partners with Azenta Life Sciences for Sanger DNA Sequencing Services. This partnership provides:

  • Next business day turnaround time.
  • Expert technical support.
  • Convenience, including on-site drop boxes and free sample shipping.
  • Preferred pricing.
