The Structural Biology Core was established to offer advanced instrumentation and support for the structural characterization of biological macromolecules to investigators at Mayo Clinic and its partner institutions.
The Structural Biology Core currently supports cryogenic sample electron microscopy (cryoEM), along with associated services such as training, data collection, processing, analysis, and data storage. Future services will include nuclear magnetic resonance (NMR) spectroscopy and X-ray crystallography.

CryoEM, the Core houses a Thermo Fisher Scientific 200 kV Glacios 2 cryogenic transmission electron microscope (TEM) equipped with a Selectris X imaging filter and Falcon 4i direct electron detector. This instrument is used for single-particle cryoEM, cryo-electron tomography (cryoET), and microcrystal electron diffraction (microED).

Targeted Biomarker Core is a specialized facility that provides immunochemical, chemistry and immune testing at an affordable cost to clinical and basic science researchers, develops and validates new assays, and improves current assay methodology.

Services include:
•Extensive test menu (see facility website)
•Assay development
•Automated chemistry analysis
•Immunoassay analysis
•Small molecule analysis
•Mass Spectrometry, LC-MS/MS and HRAM LC-MS, both high-flow and nano-flow
•Enzyme-linked immunosorbent assays (ELISA), Meso Scale Discovery (MSD), Luminex, and radioimmunoassay (RIA) procedures for various analytes
•Ability to perform most commercially available assays or kits
•Expertise in quantitation of peptides, steroids, hormone, bile acids, sugars, other small molecules

The Stem Cell and Organoid Core currently provides researchers with access to high-quality human induced-pluripotent stem cell (iPSC) production, expansion, validation, and quality control services, while strictly adhering to approved protocols, ensuring high-quality standards and consistency throughout the process.

The Immune Monitoring Core at Mayo Clinic provides services to Mayo Clinic researchers seeking to study immunological phenomena. Services include:

Designing assays to identify and quantify immune cell subpopulations
Characterizing and measuring immune function
Monitoring immunological changes in response to both specific and nonspecific stimulation
Mass Cytometry (CyTOF, Helios)
Imaging Mass Cytometry (IMC, Hyperion)
Multiplex Immunofluorescence (Akoya Phenocycler-Fusion)

The core supports experimental systems to study human and mouse models by providing expertise and standardized assays to evaluate immune functions in a broad range of diseases and therapies in models as well as in healthy human subjects with variable demographics.

The Immune Monitoring Core provides services to all Mayo Clinic faculty and staff engaged in research. Selective services are available to investigators outside Mayo Clinic.

Proteomics involves analysis and identification of protein structure and function. Through Proteomics Core, investigators at Mayo Clinic and elsewhere have access to a broad range of proteomics services, technologies and guidance to help them answer scientific questions. Toward a goal of improving patient care, the core offers services and conducts research in the areas of mass spectrometry-based differential proteomics, peptide synthesis, protein and peptide purification, and protein identification, characterization and expression.
