Pulse stable isotope labeling with amino acids in cell culture (pSILAC) coupled to mass spectrometric analysis is a powerful tool to study propagation of histone post-translational modifications (PTMs). We describe the combination of triple pSILAC with pulse-chase labeling of newly replicated DNA by nascent chromatin capture (NCC). This technology tracks newly synthesized and recycled old histones, from deposition to transmission to daughter cells, unveiling principles of histone-based inheritance.
