Figure 5.

Relative abundances of mono-, di-, and tri-methylation and unmodified proteoforms on lysine 20 observed from cell lines MCF-10A and MDA-MB-231 at different cell cycle stages. Error bars represent S.E. from two biological replicates in S and G2/M phase for each cell line, two biological replicates of asynchronous cells for cell line MDA-MB-231, and one biological replicate for cell line MCF-10A. Each biological replicate contains one to three technical replicates depending on sample amount.
