Fig. 6. Simultaneous observation of HP1 C-terminal fragment and HP1ß N-terminal fragment. Living HeLa cells transiently expressing a DsRed2-fused HP1 fragment that localized to the mitotic centromere, the N-terminal fragment of HP1ß fused with YFP, and the N-terminal fragment of CENP-B fused with CFP. From left to right, merged images of the HP1 fragment (green) and CENP-B (magenta), the HP1 fragment, CENP-B, the HP1ß fragment, and merged images of the HP1ß fragment (green) and CENP-B (magenta). Numbers on the left indicate time in hours and minutes. Scale bar, 10 µm.
