Research HighlightsProteomics via Quantitative Mass Spectrometry![]() This figure illustrates the study of proteomics using tandem mass spectrometry. Presented in the blue box are the experimental approaches used to separate (HPLC), ionize (ESI), and fragment (MS/MS) the peptides derived from a protein mixture. The corresponding primary sequence of each peptide can be determined from an experimental tandem mass spectrum (MS/MS) using the de novo or hybrid peptide identification algorithms, PILOT and PILOT_SEQUEL, which are developed within the Floudas research group using integer linear optimization (ILP). |
