Enrichment of histones from patient samples for mass spectrometry-based analysis of post-translational modifications

Aberrations in histone post-translational modifications (PTMs) have been implicated with the development of numerous pathologies, including cancer. Therefore, profiling histone PTMs in patient samples could provide information useful for the identification of epigenetic biomarkers, as well as for the discovery of potential novel targets. While antibody-based methods have been traditionally employed to analyze histone PTM in clinical samples,...
