Laser-induced DNA damage within a 4D/5D acquisition sequence

Sep 21, 2021 | Tutorials

INSCOPER markets a laser illumination controller that allows photomanipulation experiments to be performed on a video microscope within a multidimensional acquisition sequence.

This 4′ video shows an image acquisition with 3 sequences: before, during and after laser micro-irradiation to observe the recruitment phenomenon.
The cells used are U2OS cells in an 8-chamber glass holder, transfected with ALC1-GFP and labeled with Hoechst at 37°C.

The steps are as follows :
1. Define an ROI for laser irradiation.
2. Set 3 sequences for the acquisition :
     a. Before irradiation: timelapse of 50 images & 1 channel;
     b. During irradiation: Photomanipulation settings;
     c. After irradiation: timelapse of 500 images & 1 channel.
3. Choose the storage location for the dataset.
4. Start the acquisition and confirm.
5. Monitor the progress of the acquisition.
6. Visualize data.
