abberior CAGE 532
abberior CAGE 532 is a caged dye which is initially colorless and nonfluorescent. When illuminated with UV light it undergoes a rapid uncaging reaction and releases a highly fluorescent dye. The dye is optimized for excitation light around 532 nm. abberior CAGE 532 is designed for single-molecule photoswitching microscopy modes such as PALM, STORM and GSDIM and, in its uncaged form, also performs well in STED microscopy. Further, after photoactivation, abberior CAGE 532 can be tracked to analyze molecular dynamics such as diffusion, flow directions and velocities in tracking experiments (in which the fluorescence signal is observed over time after the initial release of the fluorophore).
Photophysical properties were measured for carboxylic acid in PBS pH 7.4. Values refer to the photoactivated state of the dye.
