Abstract
In this contribution the introduction of a new methodology to sequence the glycopeptides using electrospray mass spectrometry (ES-MS) as a direct and efficient approach combining structural data obtained by negative and by positive ion detection is proposed. The main characteristics of this procedure are: i) good sensitivity in the low and the high mass range ii) induction of fragmentation processes at higher orifice voltages iii) no necessity for derivatization.Keywords
