Dronpa

Dronpa is a special type of fluorescent protein used in scientific imaging that can switch between "on" (bright) and "off" (dark) states with light. When exposed to specific wavelengths, it rapidly turns off, making areas appear dark, and can be reactivated with another light to turn back on. This reversible switching allows researchers to precisely control and visualize specific proteins or structures within living cells over time. Dronpa's unique properties help scientists study dynamic processes in cells with high spatial and temporal resolution.
