Abstract

Serial derivatization by chemical reactions of analytes for mass spectrometry is disclosed. The derivatizations enhance the use of MS techniques for analyzing protein samples, particularly when the sequence of a polypeptide is determined by tandem MS/MS. Accurate mass analysis techniques are described for use in sequencing polypeptides, together with the use of sequencing data in protein analysis.
