Application

EBX1-alkyne is a hypervalent iodine reagent used for labeling cysteines. A method was developed using cysteine-reactive compounds including this one to allow for unbiased analysis of proteomic data in quantitative applications. The method uses light or heavy labeling with the isotopically labelled desthiobiotin azide (isoDTB) tag for mass spectrometry analysis. Analysis then uses the isotopic tandem orthogonal proteolysis activity-based protein profiling (isoTOP-ABPP) workflow.
