| Method | Researchers used a fluorescent labelling strategy known as CD-tagging, which tags proteins at their endogenous chromosomal locations |
| Comments | (CV=standard deviation/mean) The CV values (in human cells) were nearly constant throughout the cell cycle and were comparable to those found in bacteria and yeast (0.1–1.0) (primary sources) |
