Welcome to Targeted Metabolomics and Proteomics Laboratory
Analysis of isoflavones and their metabolites by nanoLC-MS/MS on an AB Sciex 5600 TripleTOF both increases the sensitivity of the method allowing investigation of small amounts of starting material. This approach, where the mass windows are selected AFTER the collection of MS and MSMS data, can be applied to any xenobiotic (drug, food or environmental toxin) and/or their metabolite(s). In figure A, the signal for the isoflavone genistein in a urine extract is hard discern when the mass window is 0.7 m/z; however, narrowing of the mass window to 0.05 m/z completely isolates the genistein peak.
2nd Annual Workshop on Metabolomics
June 2-5, 2014
The 2nd Annual Workshop on Metabolomics was held June 2-5 2014 on the campus of the University of Alabama at Birmingham.
The course is jointly sponsored by the National Institute of General Medical Sciences (NIGMS) as part of the NIH Common Fund Metabolomics Initiative, and the Department of Pharmacology and Toxicology at UAB.

The Targeted Metabolomics and Proteomics Laboratory (TMPL) is organized to provide a variety of analytical and technical services using mass spectrometry to UAB investigators. The laboratory has four mass spectrometers, two triple quadrupole instruments (AB Sciex 3200 and 4000), a quadrupole-linear ion trap instrument (AB Sciex 4000Qtrap), and quadrupole-TOF (AB Sciex 5600 TripleTOF). The AB Sciex 5600 TripleTOF is particularly powerful for comprehensive and targeted proteomics, lipidomics and metabolomics. The recent addition of an Eksigent microflow 200 LC provides significant improvement in sensitivity for the triple quadrupole instruments.
Two fourier transform-ion cyclotron resonance instruments - supported by NCRR grants - are in the Biomedical FT-ICR Mass Spectrometry Laboratory (http://www.uab.edu/BiomedFTICR/). Contact Dr. Matt Renfrow about use of these instruments (email@example.com; 205 996-4681).
