The NIEHS Metabolomics Core Facility (MCF) aids researchers by offering a discovery-oriented selection of mass spectrometry analyses (e.g. untargeted metabolomics) with a focus on small molecules ( < 2000 Da) of endogenous, microbial, and xenobiotic origin in a variety of matrices including cell lysates, tissues, and biofluids (e.g. plasma, urine). Expertise in small molecule mass spectrometry is complemented by state-of-the-art high-performance instrumentation. The MCF can provide analysis of samples for simple pilot projects or as involved as multi-year collaborative research. Core services include consultation in experimental design and sample processing, data acquisition, and tabular reporting of results. Additional collaborative support, including data analysis, interpretation, and assistance with reporting, is offered on a case-to-case basis.
The MCF works in conjunction with the NIEHS Mass Spectrometry Research and Support Group (MSRSG) to provide complementary chemical measurements and data analysis, and for hypothesis-oriented mass spectrometric analysis (e.g. targeted metabolomics or quantitative assays) to meet the needs of intramural investigators. Please contact either Alan K. Jarmusch in MCF, Leesa J. Deterding in MSRSG, or Jason G. Williams for consultation.

Potentially Observed Chemicals
NIEHS intramural researchers should use the contact information below for consultation and instructions on sample preparation and submission. Protocols for sample preparation are available; success in metabolomics analysis may hinge on attention to these details. Following consultation, please arrange for sample drop-off or shipping to NIEHS, Building 101, Room F025. Sample metadata must be provided when samples are submitted to facilitate accurate sample handling and data acquisition.
NIEHS Shared and Core Facilities are available to NIH researchers. Information for staff on utilizing these services may be found on the NIEHS Junction or by contacting the staff below.
