From: Multi-faceted quantitative proteomics analysis of histone H2B isoforms and their modifications
Propionylated H2B N-terminal tail chromatography and quantification. (A) H2B isoform N-terminal tails can be chromatographically resolved after propionylation. The top panel is the base peak chromatogram, and each of the following panels is an extracted ion chromatogram for different N-terminal peptide masses. Isobaric species such as H2B1D and H2B1B were completely resolved. (B) Relative quantification of H2B isoforms in HeLa samples. Mean ± SE, n = 5.
