Non-covalently-bound subunit complexes of proteins have been measured by an ion trap mass spectrometer equipped with an orthogonal electrospray ionization source. For the analysis of the generated molecular ions with high mass/charge ratios, the mass/charge range of the ion trap was extended by incr
## Abstract Study of the nonβcovalent molecular complexes in gas phase by electrospray ionization mass spectrometry (ESIβMS) represents a promising strategy to probe the intrinsic nature of these complexes. ESIβMS investigation of a series of synthetic octapeptides containing six alanine and two ly
