We describe the easy-to-use luminoscore method, based on precise acquisition conditions, requiring no calculations, and enabling tumor burden and treatment response to be monitored in mouse models. Chemistry Quantitative Proteomics Using Reductive Dimethylation for Stable Isotope Labeling Andrew C. Tolonen1,2,3, Wilhelm Haas4 1CEA, DSV, IG, Genoscope, 2CNRS-UMR8030, Évry, France, 3Université d'Évry Val d'Essonne, 4Massachusetts General Hospital Cancer Center Stable isotope labeling of peptides by reductive dimethylation (ReDi labeling) is a rapid, inexpensive strategy for accurate mass spectrometry-based quantitative proteomics. Here we demonstrate a robust method for preparation and analysis of protein mixtures using the ReDi approach that can be applied to nearly any sample type.
