Dose-response curves of LRI computed at different cell densities.

<p>The LRI response was computed at the center of the cell () and expressed as the area under the concentration-time profiles for 10 hours. Integration was performed expressing the concentrations of in nM and times in min. The ligand concentration is given in nM. The values of () are: a) 100; b) 50; c) 30; d) 15.
