Cells were previously transduced for 24 hr with CPSF6-mNeonGreen lentiviral vector (MOI 0.5) to detect CPSF6 (visualized in green). SRRM2 MLOs were detected using the TMR-HaloTag Ligand (in red) and the nuclei were stained with Hoechst (blue). Acquisitions were performed continuously for 27 min, which allowed us to see the independent formation of CPSF6 puncta, their migration towards the SRRM2 MLOs and the final fusion of CPSF6 puncta and SRRM2 MLOs.
