Max Planck Institute Takes Delivery of Waters Synapt High Definition MS System

Waters Corporation (NYSE:WAT) announced today that the world-renowned Max Planck Institute is enhancing its research on neurodegenerative diseases by adding a Waters? Synapt High Definition MS? (HDMS) System to its complement of research technologies. The Institute?s Department of Cellular Biochemistry recently took delivery of its Synapt? HDMS System to study the role of proteins in causing brain-wasting diseases including Huntington?s Disease.

HDMS System to study the role of proteins in causing brain-wasting diseasesincluding Huntington?s Disease.

?Our initial impression of the Synapt HDMS system was of a very powerful two-dimensional separation device. We wanted a system that could measurelarge intact protein complexes with high accuracy. The ability to additionally separate species by ion mobility greatly enhances the appeal of thissystem,? commented Prof. Ulrich Hartl, Director and Principal Investigator, Dr. Manajit Hayer-Hartl.

Dr. Hayer-Hartl?s research focuses on the understanding of the mechanisms by which molecular chaperones mediate protein folding and inhibit misfoldingin neurodegenerative diseases. The Synapt System will analyze the large protein complexes, and their subunit composition, that are involved in suchdiseases. Prof. Hartl and Dr. Hayer-Hartl are looking to the Synapt System to give them greater insight into protein folding, assembly, andaggregation pathways by being able to resolve, identify and characterize intermediates based on differences in conformation, something that is nearlyimpossible to do with current technology.

?We will follow folding and/or aggregation pathways in the presence or absence of chaperone systems in combination with hydrogen/deuterium exchangetechnology. The Synapt System?s Triwave technology for separating ions by their mobility will allow us to characterize our proteins of interest ingreater detail than any other mass spectrometry system currently available,? Dr. Hayer-Hartl explained.

Waters introduced the Synapt HDMS System at the American Society of Mass Spectrometry annual meeting in Seattle in June of 2006. It is the firstcommercially-available mass spectrometer to combine high-efficiency, ion mobility-based measurements and separations with a high-performanceorthogonal acceleration time-of-flight mass spectrometer.
