As of Aug. 15, 2019, we are suspending plasmid distribution from the collection. Please visit the home page to view alternative sources for the same plasmids. If you would like to request BioPlex ORF clones (Harper lab) or if you identify other clones in our collection for which you cannot find an alternative, please email us at

About Us

The PlasmID Repository is one service of the DNA Resource Core at Harvard Medical School. Our Core facility is part of the largest comprehensive cancer center in the world; the DF/HCC, bringing together the cancer research efforts of our seven member institutions: Beth Israel Deaconess Medical Center, Boston Children's Hospital, Brigham and Women's Hospital, Dana-Farber Cancer Institute, Harvard Medical School, Harvard School of Public Health, and Massachusetts General Hospital.

Funded by a grant from the National Cancer Institute, we have joined these seven renowned Harvard-affiliated medical centers into one collective force dedicated to the fight against cancer. Based in Boston, DF/HCC consists of more than 1,000 researchers with a singular goal -- to find new and innovative ways to combat cancer.

Our Mission

The mission of the DNA Resource Core is to provide researchers with inexpensive sequencing and plasmid services paired with comprehensive quality control and customer support.

Our History

PlasmID was added to the DNA Resource Core in the spring of 2004 to reduce the burden on individual labs to store, maintain and distribute plasmid clones and supporting information. Currently, our repository has ~350,000 plasmids, including most human cDNAs as well as shRNA libraries. We distribute clones widely to the community using a cost-recovery mechanism.

In addition to our PlasmID Repository service the DF/HCC DNA Resource Core also provides DNA sequencing services. To learn more click here.

Our Host

The core is hosted by the Department of Biological Chemistry and Molecular Pharmacology and the Dr. Stephanie E. Mohr in the Department of Genetics at Harvard Medical School.
