Figure 2.

Kinetics of FSH-R internalization. Binding experiments showing internalized and cell-surface FSH-R (A) or showing the internalization ratio (B) in the same culture wells, for times ranging from 4 to 60 min of stimulation with ¹²⁵I-pFSH. Results are expressed as the ratio of internalized ¹²⁵I-FSH binding versus total (membrane + internalized) binding. Data show the mean + S.E.M. of 5 independent experiments.
