A quad‐cistronic fluorescent biosensor system for real‐time detection of subcellular Ca2+ signals

British Journal of Pharmacology, EarlyView.
Background and Purpose The calcium ion (Ca2+) is a versatile cellular messenger regulating a variety of biological processes. Compounds modulating subcellular Ca2+ signals hold substantial pharmacological potential. Advances in fluorescent biosensors have revolutionised Ca2+ imaging.
