(D) Quantification of CENP-C (orange) or CENP-A (green) protein levels at the LacO array in the indicated conditions normalized to protein intensities in non-treated conditions at the mCherry-LacI-CENP-B-LacO array using CENP-A or CENP-C antibody. Each dot represents one independent experiment (>20 cell analyzed for experiment). Error bars represent SEM from 3 independent experiments.
