Peptide mass mapping involves digesting the protein with trypsin and then measuring the peptide masses using MALDI-TOF mass spectrometry. The more superior method of identifying a protein from a gel is to digest the protein with trypsin and then use liquid chromatography to separate the peptides. The separated peptides are then electrosprayed into a tandem mass spectrometer. The MS-MS data is uploaded into a database such as MASCOT for protein identification. Explain why the LC-MS-MS method is superior to the peptide mass mapping method.arrow_forward
