Genomics Services

The suite of short-read Illumina sequencers available at Clemson University allows us to harness the applications of Illumina’s MiSeq, NextSeq 550 and NovaSeq 6000 to suit your sequencing needs. Our relationship with external genomic facilities enables us to facilitate long-read sequencing using PacBio technology.

Illumina sequencers

MiSeq

MiSeq applications include targeted gene, small genome, amplicon, and 16S sequencing. As an available sequencing platform on Clemson’s main campus, we can facilitate experimental design and use of the Illumina MiSeq bench-top sequencer for your microbial studies.

NextSeq 550

NextSeq 550 applications include gene expression profiling (RNAseq), exome sequencing, and whole-genome sequencing. At the heart of our facility, the NextSeq 550 allows for high-throughput sequencing with a tunable turnaround time and data output. The NextSeq can be used for QC of libraries included in a large-scale project before sequencing on the NovaSeq6000.

NovaSeq 6000

Through our relationship with the College of Science’s Center for Human Genetics in Greenwood, SC, we can leverage the power and cost effectiveness of Illumina’s NovaSeq 6000 to suit the needs of large-scale sequencing projects. Key applications of the NovaSeq 6000 include whole-genome, whole-exome, and whole-transcriptome sequencing.

To determine your desired sequencing coverage, use one of the sequencing coverage calculators from Illumina and New England Biolabs. For further assistance, contact us.

For your long-read sequencing needs, Pacific Biosciences sequencing can be completed through our relationship with external genomics facilities. Please contact us so we can facilitate your long-read sequencing projects.

Agilent 2100 Bioanalyzer

The 2100 Bioanalyzer system features automated electrophoresis for nucleic acid quality control. Applications include DNA size and quantity, RNA quality check with RIN and protein analysis. The 2100 Bioanalyzer is utilized for DNA library QC in NGS workflows.

BioRad ddPCR

The ddPCR system provides absolute quantification of target DNA or RNA molecules for EvaGreen or probe-based digital PCR applications. Applications and examples of the QX200 Droplet Digital PCR System include copy number variation analysis (cancer biomarker studies), pathogen detection, rare mutation and sequence detection, gene expression (mRNA and miRNA), NGS library analysis, and food testing/evaluation of GMO. The ddPCR technology enables high-throughput digital PCR while using lower sample and reagent volumes thus reducing overall cost compared to qPCR methods. The method is based on water-oil emulsion droplet technology where a sample is fractionated into 20,000 droplets. PCR amplification of the template molecule occurs in each droplet. Sample partitioning allows for reliable precision which removes PCR bias found in qPCR.

RNA Isolation

Obtaining high-quality RNA is a crucial step in performing molecular techniques such as RT-qPCR, transcriptome analysis using NGS, digital PCR, and cDNA library construction. The RNA isolation protocol can be tailored to specific sample types and optimized for varying storage conditions.

DNA Isolation

Downstream applications of DNA isolation may include DNA sequencing, DNA bioanalyzer analysis and PCR. The isolation protocol may vary with sample types.

HMW DNA Isolation

Long read sequencing protocols depends on high-quality DNA samples. We aim to isolate HMW-DNA samples with mean fragment lengths of 50 kb or higher. The isolation protocol may vary with sample types.

Invitrogen Qubit Fluorometer

The Qubit benchtop fluorometer is designed to accurately measure DNA, RNA, and protein quantity. The Qubit also easily measures RNA integrity and quality. The Qubit fluorometer can be utilized for DNA library QC in NGS workflows. 

NGS Library Preparation

The NGS library preparation utilizes Illumina or other supported kits based on quantity and physical characteristics of RNA or DNA source material as well as the desired application. Library preparation involves generating a collection of DNA fragments for sequencing.

KAPA Library Quantification

KAPA library quantification is qPCR-based quantification of NGS libraries prior to pooling and used after pooling. This method enables accurate pooling of libraries for multiplexed sequencing and can also be performed after pooling as a confirmatory step before sequencing. KAPA library quantification is recommended in conjunction with Qubit and Bioanalyzer analysis.

Blue Pippin Prep

The Blue Pippin is utilized for DNA size selection (up to 50kb) for NGS. Desired target sizes or ranges of sizes are entered in software and fractions are collected in buffer. Up to 5 samples/gel cassette may be run, with no possibility of cross contamination.
