TDFragMapper: Evaluating experimental parameters for confident intact protein characterization in top-down proteomics


ABSTRACT: New software-tool allowing an easy visualization of fragment ions and thus a rapid evaluation of key experimental parameters on the sequence coverage obtained for the MS/MS analysis of intact proteins. Our tool can deal with multiple fragmentation methods. We demonstrate that TDFragMapper can rapidly highlight the experimental fragmentation parameters that are critical to the characterization of intact proteins of various size using top-down proteomics.

INSTRUMENT(S): Orbitrap Fusion Lumos

<h4>Motivation</h4>We present a new software-tool allowing an easy visualization of fragment ions and thus a rapid evaluation of key experimental parameters on the sequence coverage obtained for the MS/MS (tandem mass spectrometry) analysis of intact proteins. Our tool can process data obtained from various deconvolution and fragment assignment software.<h4>Results</h4>We demonstrate that TDFragMapper can rapidly highlight the experimental fragmentation parameters that are critical to the charac  ...[more]
