Absolute values of concentrations and of the binding/unbinding dissociation constant.

Parameters derived from Tables 2 and 3 assuming (see supplementary text S2 for details). The smaller range of values in nuclei is due to the fact that only data from a 2-component fit to the ACF are presented for this case, while in the cytoplasm the results obtained both for 2 and 3-component fits are presented and this enlarges the range of values compatible with the observations.
