Table 1 Quantification of the interaction between the RXR DBD and DNA by ITC. All data were obtained at 25°C (T = 298°K). Values represent the means values of 2–4 independent experiments and errors correspond to one standard deviation. N corresponds to the number of moles of dimer per mole of DNA except for the half-sites where N corresponds to the number of monomer per mole of DNA
