| Abstract: | FAB mass spectra of sereral synthetic oligopeptides were improved by using various matrices. They provide imformation of both molecular weights and the sequence of amino acids in oligopeptides.An empirical formula B_n+Y_n=M+ 2 was found.From B or Y ion series,the sequence of amino acids in oligopeptides could be induced. |
