Creating coveted bioluminescence colors for simultaneous myriad-color bioimaging
biorxiv(2024)
Abstract
Bioluminescence, an optical marker that does not require excitation by light, allows researchers to simultaneously observe multiple targets, each exhibiting a different color. Notably, the colors of the bioluminescent proteins must sufficiently vary to enable simultaneous detection. Here, we aimed to introduce a method that can be used to expand the color variation by tuning dual-acceptor bioluminescence resonance energy transfer (BRET). Using this approach, we could visualize multiple targets with up to 20 colors through single-shot acquisition using a color CMOS camera. Overall, this method enables simple and simultaneous observation of numerous biological targets and phenomena.
