- *Abstract
-
Rapid changes in the membrane potential of neurons and cardiomyocytes define the unique physiology of these cells. The classical means to monitor membrane potentials is patch clamp electrophysiology, a low-throughput and highly invasive technique. One current alternative is to use calcium imaging, as the agents are robust and sensitive, come in a variety of colors, and can be used in a wide range of biological contexts. Calcium imaging, however, allows only an imperfect approximation of membrane potential changes, and fast-spiking neuronal events are difficult to resolve.
Fluorescent voltage sensors can achieve fast, sensitive, and non-disruptive direct readouts of membrane potentials. UC Berkeley researchers have designed and synthesized a new fluorophore called ‘Berkeley Red’ that can be used in the context of voltage-sensing scaffolds to generate fluorescent voltage sensors.
