The core mission of the Bioanalytics Core is to provide investigators with technical expertise, education and mass-spectrometry based analytical services, and to develop new analytical approaches.
Aims of the Core
- Support current COBRE and Center projects. The Bioanalytics Core provides intellectual input, technical expertise and mass-spectrometry based analytical services, to address the needs of investigators.
- Educate and train investigators. The Core educates investigators about the principles of mass spectrometry, separations and other bioanalytical technologies. We work together to develop conceptual frameworks and execute well designed experiments.
- Develop new protocols and techniques. The Core utilizes mass spectrometry to design high sample and information throughput methods to accommodate the growing needs of researchers. Core personnel attend conferences and workshops to educate themselves about advancements in the field. The Core continues to expand its knowledge-base and technical expertise to satisfy the future needs of the Center.
Facilities & Instrumentation
The Mass Spectrometry laboratory is in the Delia Baxter II Biomedical Research Building (580 South Preston Street) on the University of Louisville Health Science Campus. It occupies over 2000 sq. ft of laboratory space and provides rich and diverse resources from which the investigators interface to develop their own independent research programs.

Currently, our Core has excellent targeted analytical workflows based on the state-of-the art UPLC/UHLPC-MS/MS systems with triple-quadrupole analyzers and GC-MS. In August 2020 the Core added a high resolution, state-of-the art Waters Synapt XS LC-MS system (obtained through the NIH shared instrumentation grant mechanism – S10 OD026840).
The Bioanalytics Core facilitates characterization and quantitation of small molecular weight analytes in biofluids, tissues and cells.
