The Genomics & Epigenomics Shared Resource (GESR) provides diverse services such as next generation sequencing (NGS), single-nucleotide polymorphism (SNP) genotyping, copy number variation (CNV) analysis, DNA methylation analysis, and mRNA/miRNA expression profiling. The GESR uses state-of-the-art instruments and assays to provide these services. These instruments include the Illumina NextSeq 550, Illumina MiSeq, Illumina iScan, NanoString nCounter SPRINT Profiler, Agilent Microarray System, Affymetrix Microarray System, and Applied Biosystems QuantStudio Real-Time PCR (RT-PCR) System, and Covaris M220 Focused-ultrasonicator. The Mid-Atlantic Shared Resources Consortium provides access to additional instruments including Illumina HiSeq 4000 and Pacific Biosciences RS II. To facilitate these services, the GESR assists users in DNA/RNA quality assessment as well as DNA plating and assay preparation using Agilent Bioanalyzer and Beckman Multimek NXP Robotic Liquid Handling System, respectively. In addition, the GESR provides bioinformatics support for omic data analysis and training for user-operated instruments (e.g., RT-PCRs, plate readers, spectrophotometers, and densitometers).
