Description 

The slow-response potential-sensitive probe, DiBAC4(3) can enter depolarized cells where it binds to intracellular proteins or membrane and exhibits enhanced fluorescence and a red spectral shift. Increased depolarization results in additional influx of the anionic dye and an increase in fluorescence. Conversely, hyperpolarization is indicated by a decrease in fluorescence.

Notes 

1. There are quenching problems with fluorescent dyes. Please avoid light to slow down the fluorescence quenching. 

2. For your safety and health, please wear lab coats and disposable gloves.
