摘要：

A series of small peptides has been studied by negative-ion fast-atom bombardment mass spectrometry with collision-induced dissociation. It has been found that by derivatizing peptides with 4-aminonaphthalenesulphonic acid in a peptide linkage at the C-terminus, negative-ion formation can be enhanced and fragmentation in collision-induced dissociation reactions controlled. The peptide-naphthalenesulphonates show charge-remote fragmentations and the resultant spectra give sequence information.
