The video shows live FUCCI mESC that were imaged for over 48 hours with Nanolive’s 3D Cell Explorer-fluo. A holotomographic image was taken every 14 seconds while a double channel (green and red) epifluorescence image was only taken every 30 holotomographic frames (7:30 minutes). The difference in acquisition rate was performed to reduce fluorescence related phototoxicity.
*Please note that the latest fluorescence image is displayed over the following 30 holotomographic images until a new one is acquired, for visualization purpose. The mismatch between the two signals is due to this image processing choice.
