Abstract

De novo sequencing is an effective method for identifying unknown peptide sequences from their tandem mass spectra. This unit briefly introduces how this can be done manually. A protocol for using the PEAKS online software for automated de novo sequencing is described. Finally, we show how to use the PEAKS scores to validate the de novo sequencing results.
