Often there are many spectra remaining after a database search that have promising de novo sequences, leaving you wondering what the source of these spectra are. We call these ‘de novo only spectra’. Multi-Round search gives you the ability to search only these spectra. This helps you:

  • Remove spectra produced from contaminants
  • Find endogenous peptides in a enzyme digested sample
  • Refine search parameters to identify difficult targets
