PacBio Long-read NGS Sequencing

The PacBio Sequel IIe long-read sequencer at UNC provides a unique and essential capability for genomic research. Its ability to generate reads between 6,000 and 20,000 base pairs fills a critical gap in the university’s sequencing infrastructure, enabling the generation of complete genomes rather than limited exome sequences. This is particularly beneficial for the detection of DNA translocations and repeat contractions across diverse organisms, including human, murine, viral, and bacterial genomes. Furthermore, the instrument’s capacity to sequence complete mRNA transcripts using new chemistry allows for the direct identification of spliced isoforms and splice junctions, a significant improvement over inferences drawn from short-read data. Crucially, PacBio’s HiFi sequencing technology delivers high base call accuracy (≥Q30) and consensus quality, surpassing that of Oxford Nanopore. This elevated accuracy is paramount for the analysis of clinical samples and addresses the NIH’s stringent requirements for rigor, robustness, and reproducibility in scientific investigations. Therefore, the PacBio Sequel IIe is indispensable for advanced genomics research at UNC.

Ion Torrent PGM and Ion Torrent S5 NGS

Next Generation Sequencing services (DNA and RNAseq) are available by the Vironomics Core for several sequencing platforms. Please see the sequencing tab , unofficial guide, and/or sample submission for details.

Utilizing our Ion Torrent sequencers (more reads) allows most runs to accommodate a greater number of samples with greater coverage than the GS Junior. This commercially available option, Precision ID NGS, will allow for a plug-n-play analysis, which should decrease the need for specialized bioinformatics.

Plasmid Verification

We have had success with plasmid verification for various clients using the GS Junior. We are now transitioning this to our newest instrument, Ion Torrent S5, which will allow for greater sequencing depth and lower cost/plasmid.

Services & Fees

Please note that the fees were changed June 2025.

qPCR (real-time PCR) arrays available

We offer various qPCR arrays that include anywhere from 5 to 768 primer pairs per assay. Our assays include: KSHV, EBV, HCMV, HSV-1, HSV-2, RRV, Viral Load, microRNA, NFkappaB, and P53response.

Data Analysis

As a Vironomics Core, we not only perform the assay services that generate data, but we also offer analysis services to assist transforming the raw data into ready-to-use data.
