Proteomics Facility

0

The Proteomics Center analyzes protein/peptide/small molecule samples with the help of mass spectrometry. The Proteomics technical staff measure intact masses of proteins/peptides/small molecules, identify peptides based on their sequence, and discover post-translational modifications. Comparisons of protein expressions between different samples are conducted. The center has four different mass spectrometers: a Matrix-assisted laser desorption/ionization time-of-flight mass spectrometer; a triple quadrupole mass spectrometer; a linear ion-trap mass spectrometer; and a high-resolution, high mass accuracy hybrid mass spectrometer with four different activation methods (Thermo LTQ Orbitrap XL with ETD). In addition, equipment for running 2D gel electrophoresis and analysis are also present. For additional information, services and fees please link to: http://www.osa.sunysb.edu/Proteomics/
