Abstract:In this work, we developed a membrane-enriched stable isotope isobaric-labeled carrier channel (meSIILCC) for mass spectrometry-based thermal stability assay (MS-TSA). A proof-of-concept study demonstrated that the meSIILCC method could modestly improve membrane protein (MP) detection in MS-TSA experiments. An enhancement of 10% in identifications of membrane-proteins was observed in the meSIILCC group. Hydrophobicity analysis of the identified and quantified peptides using the grand average of hydropathy inde… Show more
