Description

Application

OxMet2-alkyne is an oxaziridine probe that can be used to label methionines. A method was developed using cysteine-reactive compounds including this one to allow for unbiased analysis of proteomic data in quantitative applications (Zanon et al. 2021). The method uses light or heavy labelling with the isotopically labelled desthiobiotin azide (isoDTB) tag for mass spectrometry analysis (Zanon et al. 2020). Analysis then uses the isotopic tandem orthogonal proteolysis activity-based protein profiling (isoTOP-ABPP) workflow (Weerapana et al. 2010, Backus et al. 2016)
