Which technique has almost eliminated the need to chemically sequence a polypeptide?

Question

Quizplus · Accepted Answer

Peptide mass fingerprinting using MALDI-TOF (Matrix-Assisted Laser Desorption/Ionization Time-of-Flight) has significantly reduced the need for chemical sequencing of polypeptides. This technique identifies proteins by cleaving them into smaller peptides, then ionizing and measuring the mass of these peptides. The resulting mass fingerprint can be matched against known protein databases to identify the protein without needing to sequence it chemically.
