Tandem mass spectrometry of intact Cystatin SN, mass 14319 Da. A 14-charge parent ion (inset) was subjected to CAD (A) and ECD (B) on a hybrid linear ion-trap FTICR mass spectrometer. Peaklists were extracted from the datasets using Xtract software prior to processing with Prosight software. Fragment ion mass accuracy was better than 5 ppm RMS.
