Services

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). Measurements provide the ability to perform relative quantification to determine which chemicals (known or unknown) are changing between samples. Alternatively, untargeted approaches can be used to ascertain and describe the chemical constituents of materials. Applications of our untargeted approaches include basic biological research, exposure research, biomarker discovery, translational research, clinical research, epidemiological research, and more.

The MCF offers our expertise for single sample analysis (e.g. metabolite identification), small pilot projects, and full projects (up to 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 instrumentation, ultra-high performance liquid chromatographs and mass spectrometers, available in the MCF are state-of-the-art and offer a variety of measurement capabilities. Ultra-high performance liquid chromatography (UHPLC) coupled to high-resolution mass spectrometry (HRMS) is the most common technique used in the MCF. We use different data acquisition strategies including single reaction monitoring (SRM or PRM), tandem mass spectrometry (aka MS/MS or MS2) via data-dependent acquisition (DDA), MS2 via iterative data-dependent using AcquireX, and others. The MCF utilize ion mobility spectrometry coupled to UHPLC-HRMS to distinguish isomers via their gas-phase collision cross section (CCS).

And emerging capability is hypothesis-oriented analysis from which absolute quantification can be performed. Hypothesis-oriented mass spectrometric analysis (e.g. targeted metabolomics or quantitative assays) will be offered to complement the measurements offered by the NIEHS Mass Spectrometry Research and Support Group (MSRSG). The MCF works in conjunction with the MSRSG to meet the needs of the intramural research program.

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.
