Figure 2.
Denaturation-purified Dex-BSA (100 nM) retained its effect on GR nuclear translocation. A. N42 cells expressing GR-GFP were treated with purified Dex-BSA and imaged at 0, 5, and 20 min. Lower panels show magnifications of the boxed regions in the upper panels. B. Time course of GR-GFP translocation to the nucleus, measured by fluorescence intensity in a nuclear region of interest. The kinetics of GR nuclear translocation induced by the unpurified (Dex-BSA) and the purified Dex-BSA were comparable to each other, but were both slower than the free Dex-induced nuclear translocation of GR (Dex).
