Abstract:
Stable isotope labeling by amino acids in cell culture (SILAC) and iodoacetyl tandem mass tag (iodoTMT) are well-implemented mass spectrometry-based approaches for quantification of proteins and for site-mapping of cysteine modification. We describe here a combination of SILAC and iodoTMT to assess ongoing changes in the global proteome and cysteine modification levels using liquid chromatography separation coupled with high-resolution mass spectrometry (LC-MS/MS).
