Biomolecular Analysis Service Line
Mayo Clinic's Biomolecular Analysis Service Line comprises high-complexity cores offering top-of-the-line biomolecular research support. Cores focus on genome analysis, proteomics, metabolomics, immunochemistry and cytogenetics.
Specialized services include:
- Gene sequencing, gene analysis and genotyping.
- Protein identification, quantification and purification.
- Automated chemistry analysis, immunoassay analysis and small molecule analysis.
- Cell culture, fluorescence in situ hybridization (FISH) and production of novel FISH probes.
Cytogenetics Core
The Cytogenetics Core analyzes human and animal model research samples using methods such as:
- Cell culture.
- Routine cytogenetic analysis.
- Interphase and metaphase FISH.
- Homebrew FISH probe production of custom, novel FISH probes.
The core also provides training on molecular cytogenetic techniques, equipment, setup and analysis so that researchers can use the core's facilities to process and analyze their own specimens.

Genome Analysis Core
The Genome Analysis Core offers researchers a synthesis of three primary services — sequencing, gene expression and genotyping — that together provide comprehensive genomic analyses. Services provide clinicians and researchers with comprehensive information about differences and changes in a person's genetic makeup, advancing genetic and genomic understanding of many diseases and treatments.

Immune Monitoring Core
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.
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. Currently, services are not available to investigators outside Mayo Clinic.

Metabolomics Core
The Metabolomics Core offers mass spectrometry techniques to support research in disease diagnosis and prevention by assisting investigators with profiling the metabolites involved in micro (cellular) and macro (organ) physiology. The core offers stable isotope-labeled metabolic studies in both human and animal models.
Services include:
- Three complementary techniques for untargeted metabolomics profiling.
- Targeted panels for mass spectrometry quantification.
- Isotope-labeled ratio measurements.
- Access services.
The core offers a full-service facility with applications for high-field nuclear magnetic resonance (NMR) spectroscopy and biochemical and biological systems microscopy. The facility contains high-field, state-of-the-art NMR spectrometers for data acquisition; computers for NMR data analysis; and a fully equipped wet laboratory for sample preparation.

Spatial Biology Core
The Spatial Biology Recharge Facility evolved from studying the relationship between how genes function during the process of transformation of normal cells to cancer cells. The facility offers investigators tools and collaboration for conducting basic cellular research. This testing enables a better understanding of cancer cells and reveals possibilities for developing novel treatments.
The facility was one of the first to use NanoString Technologies' nCounter bar coding technology. This technology uses color-coded molecular bar codes that can hybridize to many types of target molecules.
Over the years, the facility has done alpha and beta testing of most of the cancer-related products created and marketed by NanoString Technologies. One of the facility's major services is analyzing messenger RNA abundance in formalin-fixed and paraffin-embedded (FFPE) clinical samples.
The Spatial Biology Recharge Facility has long had a productive collaboration with NanoString Technologies. The facility was one of four sites to beta test the GeoMx Digital Spatial Profiling platform. Beta testing began in September 2019 and led to the first commercial instrument shipping in January 2020.
The facility has since used the GeoMx platform to process samples from solid tumors, including breast, lung, colon, pancreatic, hepatocellular and ovarian cancers, and cholangiocarcinoma. During processing, the facility measures spatial expression of protein and RNA. Spatial context can refer to the 2D or 3D space within tissue. This helps researchers understand the complex interactions between cells and molecularly characterize processes, cells and genes.

Spatial Multiomics Core
The Spatial Multiomics Core provides cutting-edge spatial genomics, epigenomics and transcriptomics technologies and expertise. It supports patient-focused and experimental model-based biomedical discovery by developing and implementing integrated genomic, epigenomic and transcriptomic approaches to interrogating cells in their native tissue microenvironment and offering these technologies as a core service to Mayo Clinic investigators.
This full-service core assists investigators with all aspects of their project needs from consultation and experimental design through data analysis and delivery of materials for grants and manuscripts.

Targeted Biomarker Core
The 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:
- Biomarker quantification and analysis.
- Automated chemistry analysis.
- Immunoassay analysis.
- Small molecule analysis.
- Enzyme-linked immunosorbent (ELISA), Meso Scale Discovery (MSD), and radioimmunoassay (RIA) procedures for various analytes.
