Coupling Luciferase Activation and BRET Enables High-Contrast Red-Window Calcium Imaging

Genetically encoded bioluminescent calcium indicators enable excitation-free imaging of Ca2+ dynamics with low background, no photobleaching, and improved tissue penetration.

Genetically encoded bioluminescent calcium indicators enable excitation-free imaging of Ca2+ dynamics with low background, no photobleaching, and improved tissue penetration. However, many exhibit lower dynamic ranges than their fluorescent counterparts, motivating the…
