Metabolomics Core
Metabolomics Mass Spectrometry Lab
Advancing Metabolomics Research
The Metabolomics Core at the Fralin Biomedical Research Institute at VTC is dedicated to supporting biomedical research through cutting-edge mass spectrometry techniques for the detection and quantification of small molecules (metabolites) in biological samples. Directed by Dr. Junco Warren, an assistant professor at the research institute with extensive expertise in metabolomics analysis of tissue and plasma samples, the core is committed to advancing our understanding of metabolism in health and disease.
Metabolomics is the comprehensive study of metabolites — small molecules that represent a wide variety of chemical compounds, including amino acids, lipids, organic acids, drugs, and environmental chemicals. These metabolites, collectively referred to as the metabolome, can be altered by physiological or pathological stimuli, providing crucial insights into biological processes.
The Metabolomics Core operates two state-of-the-art mass spectrometry systems:
GCMS - Shimadzu GCMS-TQ8050 NX EI/CI/NCI: This triple-quadrupole system is capable of ultra-trace analysis down to the femtogram level. With advanced detection technology and noise-reduction capabilities, it is ideal for detecting sugars, glycolysis intermediates, TCA cycle intermediates, amino acids, fatty acids, and a variety of other compounds.
LCMS — Agilent 6545 qTOF UHPLC-MS: This high-resolution system is used for a wide range of metabolomics applications, including the analysis of acylcarnitines, adenine nucleotides, and many other metabolites. It offers high sensitivity and precision for both targeted and untargeted metabolomics studies.
Rate Schedule (internal / external)
- Technician rate (per hour): $29 / $49
- Research Scientist rate (per hour): $41 / $66
- GCMS rate (per sample, minimum of 10): $150 / $242
The Metabolomics Core accepts a variety of biological samples for analysis, including but not limited to:
