Overview of Services
Research Services
Members of the Sequencing and Discovery Genomics team consult with researchers to understand their unique needs, and provide expert guidance, tools, and assistance for project completion. They also participate in cutting-edge application and technology development, and provide education and training to researchers in multiple areas of genomics.
As Stowers was one of the first institutes in the Midwest region to offer Next Generation Sequencing (NGS) through Illumina platforms, the team has extensive experience with this technology. Rapid high-throughput, short-read sequencing is offered in-house using the Illumina NGS platforms. For projects requiring long-reads, outsourcing for PacBio sequencing is offered using trusted external partners. In addition to NGS, the team performs high-throughput plasmid preparation and Sanger sequencing.

Anoja Perera
Director, Sequencing and Discovery Genomics
Stowers Institute for Medical Research
With a B.S. degree in biology, Anoja Perera developed her skills in DNA sequencing, genomics applications, automation, and high throughput processing while working with Raju Kucherlapati, Ph.D., on the original Human and Mouse Genome Projects. After several years’ experience as group leader for sequencing at the Harvard-Partners Center of Genetics and Genomics in Cambridge, Mass., she joined the Stowers Molecular Biology group. Perera served as senior lab manager from 2006 until 2019 when she was appointed Director of the Sequencing and Discovery Genomics group. In this role, Perera seeks to advance research by making cutting-edge sequencing technologies available to the scientific staff. For many years, Perera has been an active member of the Association of Biomolecular Resource Facilities and served on multiple committees including the organization’s Executive Board.
Omics and Sequencing
Chromatin Immunoprecipitation Sequencing, or genome-wide DNA/protein interaction sequencing, DNA sequencing, whole transcriptome and single cell RNA sequencing are just some of the services we provide to Stowers scientists.
Next Generation Sequencing
The Sequencing team at the Stowers Institute began offering Next Generation Sequencing (NGS) to the Institute in September 2007 on the Illumina Genome Analyzer (GA). We have continuously updated and added sequencing instruments over the years to stay current with advances in technology and Institute demand. The current Illumina NGS sequencers available at Stowers are the NextSeq 2000, NextSeq 500 and MiSeq. We also have quick access to the NovaSeq 6000 through our neighbors at KUMC. Currently, we use Illumina sequencing systems for many different applications.
Single Cell Genomics
Interest in single cell sequencing applications has greatly increased in recent years as technologies have been developed to enable the study of heterogeneity that exists at the individual cell level. The Sequencing team offers single cell sequencing services mainly using 10X Genomics workflows.

Spatial Transcriptomics
The spatial organization of cells within a given tissue plays a crucial role in determining their overall function. Driven by the importance of understanding this organization, spatial transcriptomics is quickly coming to the forefront of new Next Generation Sequencing (NGS) applications with the ability to map cellular gene expression back to a specific location within the tissue. The Sequencing team has experience with two spatial transcriptomics workflows, namely Slide-seqv2 (a method published in Nature Biotech (2021) by Stickels et al) and Visium, a commercialized kit from 10X Genomics.
Sanger Sequencing
Sanger based, dye-terminator sequencing of plasmids, PCR products, BACs and Lambda DNA is performed using two ABI 3730xl 96-capillary DNA analyzers. The reactions are performed with modified versions of Applied Biosystems (Big Dye Terminator ver. 3.1) protocols. Unincorporated nucleotides are removed by exclusion columns from Edge Biosystems or by SPRI technology from Agencourt.
Automation for Sequencing
Our team members have extensive experience with automation and we have invested in cutting edge equipment to allow for processing of samples in both 96-well and 384-well format. We offer high throughput processing of samples to either feed into our Sanger Sequencing or Illumina sequencing. Often, reactions are miniaturized using specialized instruments that allow low volume pipetting to reduce costs significantly.
