Isotopic analysis was carried out using an in-line elemental analyzer (EA, CHNS-O EA1108, Thermo Sci.) and isotope ratio mass spectrometer (IRMS; Finnegan Delta Plus XP, Thermo Sci.). EA-IRMS run sequences were setup with pre-weighed pugel and acetanilide standards, and the pelleted ...
ISOTOPIC DISTRIBUTIONSINTERNAL STANDARDSO-18PROTEINSIDENTIFICATIONSTRATEGYA method is described for the identification and relative quantification of proteomes using accurate mass tags (AMT) generated by nLC-dual ESI-FT-ICR-MS on a 7T instrument in conjunction with stable isotope labeling using O-16/O...
