The assessment of the ligand-mediated mobility of GFP-ERβ (A) and GFP-ERβEBD (B) by FRAP. Transient transfection and processing of HeLa cells for FRAP were carried out as described in legend of Fig. 2. The normalized mean fluorescence recovery of GFP-ERβ species without (NL) or with a ligand from three independent experiments with a minimum of five individual cells per experiment was graphed without SEM, which was less than 15% of the mean.
