Abstract:
A method of detection of amino acid sequences and/or identification of proteins and peptides is based on derivatization of peptides or proteins using compounds comprising two or more sulfonyl groups, and subsequent analysis of the derivatized analytes using a mass spectrometer in its negative mode of operation.
