【摘要】 采用合适的底物可以使寡肽的ＦＡＢ质谱图同时提供有关肽的分子量和氨基酸的信息。发现了经验公式Ｂ＋Ｙ＝Ｍ＋２，根据这一公式可以方便地推导出肽的氨基酸序列。更多还原

【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.更多还原
