PTM Finder Software
Shimadzu’s data mining software is used to investigate post-translational modification in complex protein samples, including data for hypothetical, novel modifications. The software integrates with Shimadzu’s AXIMA line of MALDI mass spectrometers. Users can identify peptide sequences carrying one or more modifications using MS/MS data and MS/MS Ion Search. The PTM Define module allows users to define their own hypothetical modifications and screen the remaining data for shifts in fragment masses, neutral losses and/or diagnostic ions.
