IM\u2010MS is a suitable method for the study of IDPs which provides an insight to conformations that are present in solution, potentially enabling the analysis of lowly populated structural forms. Here, we describe the IM\u2010MS data of two IDPs; \u03b1\u2010Synuclein (\u03b1\u2010Syn) which is implicated in Parkinson's disease, and Apolipoprotein C\u2010II (ApoC\u2010II) which is involved in cardiovascular diseases. We report an apparent discrepancy in the way that ApoC\u2010II behaves in the gas phase. While most IDPs, including \u03b1\u2010Syn, present in many charge states and a wide range of rotationally averaged collision cross sections (CCSs), ApoC\u2010II presents in just four charge states and a very narrow range of CCSs, independent of solution conditions. Here, we compare MS and IM\u2010MS data of both proteins, and rationalise the differences between the proteins in terms of different ionisation processes which they may adhere to.<\/jats:p>","DOI":"10.1002\/pmic.201400605","type":"journal-article","created":{"date-parts":[[2015,4,29]],"date-time":"2015-04-29T06:33:40Z","timestamp":1430289220000},"page":"2872-2883","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":60,"title":["Relating
