Research

Our research involves the application of liquid chromatography–mass spectrometry (LC-MS) methods to analytical problems of importance.  The Chemistry Department houses an Agilent 1100 HPLC–SL Ion Trap system that allows chromatographic separation and mass spectral identification of analytes, including Mass Spectrometry/Mass Spectrometry (MS/MS) methods. In previous work the instrument was employed to verify the site-specific incorporation of unnatural amino acids in proteins. Currently, we are working with the Clinic for Special Children in Strasburg, PA to address clinical aspects of GM3 synthase deficiency, a rare autosomal recessive epilepsy syndrome ob-served in the Amish population. A key component of the project is the development and implementation of analytical methodologies for the analysis of ganglioside molecules using LC-MS and fluorescence techniques.
