An orange calcium-modulated bioluminescent indicator for non-invasive activity imaging.

ABSTRACT: Fluorescent indicators are used widely to visualize calcium dynamics downstream of membrane depolarization or G-protein-coupled receptor activation, but are poorly suited for non-invasive imaging in mammals. Here, we report a bright calcium-modulated bioluminescent indicator named Orange CaMBI (Orange Calcium-modulated Bioluminescent Indicator). Orange CaMBI reports calcium dynamics in single cells and, in the context of a transgenic mouse, reveals calcium oscillations in whole organs in an entirely non-invasive manner.
