Fig. 5. Mobility of GFP-Hsp70 and GFP-Hsp70 (K71E) relative to GFP in (A) cytosol and (B) nucleus. GFP or GFP-Hsp70 were bleached and the fluorescence recovery after photobleaching was measured. The fluorescence recovery after photobleaching is shown for GFP (
), GFP-Hsp70 (
) and GFP-Hsp70(K71E) (
).
