Approximate abundance of several modified forms of histone H3 for the elution time window of 168–212 min. The majority of the modified forms in this time range have a single acetylation of the lysine in either position 14, 18, or 23. It is interesting to note the chromatographic resolution with respect to the acetylated position where K14ac elutes first, K18ac elutes second, and K23ac elutes last.
