Methods: Collection and analysis of high resolution CID, HCD, ETD, and UVPD data on various proteins at various energies or reaction times. Results: Each fragmentation mechanism generates unique data that, together, maximizes sequence coverage for improved protein identification and proteoform characterization. Considerations for optimizing each dissociation mechanism with respect to proteins representing a MW range from 9kDa to 50kDa are presented.
