Penn Genomic Analysis Core - DNA Sequencing Laboratory



Penn Genomic Analysis Core will be opening for all services on June 8st, 2020 in accordance with the guidance from Perelman School of Medicine’s Phase I reopening. During this time we will be accepting samples for Sanger, molecular biology work, NGS, BioAnalyzer, fragment analysis, cell culture work, microarray and real-time PCR. If you plan on submitting samples please work with us by scheduling a time to drop off samples through email for all RNA BioAnalyzer, DNA preps and any samples that cannot be delivered to the drop boxes. Sanger samples, Fragment Analysis, and DNA BioAnalyzer samples should be delivered to our drop boxes in BRB lobby, Johnson Pavilion lobby, and Smilow lobby in a small plastic bag with printout of submission. Samples will be picked up at 11AM every weekday. We kindly ask that you do not enter our lab. Please knock on the glass outside the lab so we can meet you in the hallway to pass samples to us. Please email the following people for sample drop off instructions and times:

Overview of Services

DNA Sequencing Facility was founded in 1994 as an Abramson Cancer Center (ACC) core. In 2014, the Perelman School of Medicine (PSOM) and Abramson Cancer Center (ACC) combined two NCI CCSG supported cores, the DNA Sequencing Facility and the Molecular Profiling Facility to consolidate genomic services under a single umbrella Core. The resulting Shared Resource, the Penn Genomic Analysis Core was and continues to be directed by Dr. Tapan Ganguly.

DNA Sequencing Facility offers sequencing services on three platforms, gold standard Sanger sequencing on ABI capillary sequencers, next-generation sequencing (NGS) on Ion Torrent PGM and S5 and, Illumina MiSeq and Next-Seq. along with experimental design and data analysis.

The NGS service includes library preparation for multiple applications including targeted sequencing, RNA-Seq and Exome-Seq. Free consultation is provided for project planning and experimental design. Data analysis service is performed in consultation with the investigators.

The capillary sequencers also enable microsatellite genotyping and fragment analysis for VNTR, SNaPshot and Human Cell Line Authentication.

The molecular biological services include PCR, cloning, subcloning, mutagenesis, construct preparation and, plasmid DNA preps at different scales.
