NOTICE: To All Duke Proteomics and Metabolomics Shared Resource Users

The Duke Proteomics and Metabolomics Shared Resource is undergoing a partial reopening under guidance from the Duke School of Medicine. In this ‘Spin-Up’ Phase we are operating under the following guidelines, which are designed to ensure safety for our colleagues and our lab scientists.

  1. To minimize the number of staff in the facility at any given time, all DPMSR staff are working from home as much as possible as possible. Only tasks requiring hands-on effort in the laboratory will be performed there. 
  2. All project discussions and data return discussions are to be made using WebEx/Zoom or by phone. Data delivery will continue to be made using the on-line Express Data Repository.
  3. All scientists and visitors are required to wear a face mask while in the Chesterfield. These should be in-place before entering the Chesterfield. Note that entry from the Chesterfield is to be made only from the front of the Building facing W. Main St. and exit from the building is to be made using the back doors by the railroad tracks.
  4. In spin-up, all sample deliveries must be made directly to the Chesterfield and only by prior scheduling arrangement with the project lead (Drs. Moseley, Thompson, Soderblom or Foster). An in-person drop box system will be used at front door, allowing for a semi-direct hand-off while maintaining social distancing and using appropriate PPE. 

We look forward to working with you again.

Please contact Dr. Arthur Moseley with any questions or concerns regarding our lab.

If you have questions about specific ongoing projects, please contact your project lead:

The School of Medicine, the Duke Center for Genomics and Computational Biology (GCB), and the Duke Cancer Institute have collaborated with the Proteomics and Metabolomics Shared Resource to provide protein characterization resources for the Duke Research Community. These services include protein identification and protein quantitation from a wide variety of sample types, from simple mixtures like gel spots and bands to complex mixtures like protein complexes, cell lysates, and plasma. The facility is located on the third floor of the Chesterfield Building, 701 West Main Street.

The Proteomics and Metabolomics Shared Resource uses mass spectrometry as the key technology for qualitative and quantitative protein characterization. Our principal approach for protein analysis is 'bottom-up' proteomics, where all proteins are proteolytically digested, producing peptide surrogates (signature peptides) of the original proteins.

Protein identifications are made using state-of-the-art database search engines running on a dedicated high speed Blade cluster with the capability of searching standard or custom protein databases.

Protein quantitation can be accomplished using a "gel free, label-free" technology that provides both relative quantitation (test vs. control) and absolute quantitation (nanograms protein). Alternatively, isotope-coded (labeled) samples can be analyzed to provide relative quantitation information.

Facility News

We Relocated!

The Proteomics & Metabolomics Shared Resource has moved into a custom-designed lab space in the newly renovated Chesterfield building in downtown Durham. Our new lab space will expand our capabilities and capacity to support Duke University's research needs. The Chesterfield is located at 701 W. Main Street, in the heart of Durham's Innovation District.

  • This state-of-the-art lab will allow us to provide the best possible resources for researchers at Duke and around the world. We expect to continue adding new instruments and technologies in the coming years to respond to the needs of Duke researchers, boost overall sample capacity, and reduce turn-around time.
  • We will continue to provide direct contact with researchers on campus. Faculty and staff will be available during and after the transition for face-to-face consultations in the CIEMAS building or the Chesterfield building, according to your preference.
  • Sample drop-off options is available on campus in the CIEMAS building, room 2208B. Researchers may also drop off samples at the Chesterfield building.


Duke Translational Research Institute Core Services vouchers are awarded on a quarterly basis. The facility is pleased to announce that proteomics is having an impact in these voucher studies; approximately 50 percent of the 2010 awards have utilized proteomics for their studies.

Acknowledging the Input of Core Facilities

A common question of labs when working with core facilities is how best to acknowledge or include as authors the core in the publication of results and interpretation provided by the core. The Association of Biomolecular Resource Facilities (ABRF) has published recommended guidelines for authorship on manuscripts, and we ask our users to consider these guidelines when publishing data generated by the Proteomics and Metabolomics Shared Resource. Ultimately, the decision to include or acknowledge is decided by the senior author (or PI) on the publication. Because a publication record is essential to ensure a high-quality core facility and for the professional development of its staff, we ask our users to carefully consider the input of core members to scientific publications.


For all publications that include data generated in the Proteomics and Metabolomics Shared Resource, we kindly request that you acknowledge this support:

We thank the Duke University School of Medicine for the use of the Proteomics and Metabolomics Shared Resource, which provided _________ service.
