Research Application Overview

Voltage-sensitive dyes (VSDs) are small molecules that convert changes in voltage inside cells to visible changes in fluorescence. Voltage-sensitive dye imaging is used to record these changes in fluorescence, usually with a microscope.

They are an important tool for researchers who need to measure electrical signaling in cells for several main purposes:

Neuroscience Research

Neuroscience researchers study neurological disorders such as Alzheimer’s and Autism

Commonly Used:

Cardiac Research

Cardiac researchers study conditions such as Arrhythmogenic Cardiomyopathy

High Throughput Screening

Drug developers test the efficacy or safety of new therapeutic compounds

New & Novel Applications

Researchers use cancer cell lines to track hyperpolarization propagation
