Heat map of the MS1 scans vs. deconvoluted mass of the GluC-digested N-terminus of histone H3 spectra treated with (a) butyric acid and (b) DMSO after WCX-HILIC separation. The histone deacetylase inhibitor butyric acid-treated H3 histones showed the most intense ions with 2 and 3 acetylations, while the DMSO-treated H3 histones showed the most intense ions with 0 and 1 acetylations
