Model No.: Voyager-DE PRO Manufacturer: Applied Biosystems, Inc. Location: RRC-West, 550 PHARM

The Applied Biosystems, Inc. Voyager-DE PRO high performance benchtop matrix-assisted laser desorption ionization/time-of-flight (MALDI/TOF) mass spectrometer provides high mass range, high sensitivity, and high throughput MALDI/TOF mass spectra of biopolymers such as proteins and oligonucleotides as well as organic prepolymers and other large organic molecules. Mass range is over 300,000 with resolution in linear mode > 1000 for myoglobin and resolution in reflectron mode > 7000 for angiotension. It uses a 337 nm nitrogen laser. Sensitivity is 5 fmol of neurotensin. It is suitable for proteomics applications such as peptide mapping, peptide sequencing using post-source decay (PSD), and protein identification. The Proteomics Solution 1 (PS1) System consists of a stand-alone computer workstation for database searching as part of proteomics protein identification and a robotic workstation that can prepare samples from 96-well plates for high throughput by spotting a 100 well plate with sample, reference, and MALDI matrix.

The Applied Biosystems, Inc. Voyager-DE PRO PS1 was purchased in 2002 with NIH grant to Dr. Richard B. van Breemen.
