Descripción general
Abberior CAGE 590 is a masked 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 opens up the red fluorescent regime for CAGE dyes. It can most effectively be excited from 560 to 600nm.
Abberior CAGE 590 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 markers can be tracked in confocal and epifluorescence microscopy to analyse molecular dynamics such as diffusion, flow directions and velocities, e.g. are tracking experiments in which the fluorescence signal is observed over time after the initial release of the fluorophore.
Key Features
Absorption Maximum, λmax: 262, 325, 351 nm (non-activated, PBS, pH 7.4)
595 nm (photoactivated, PBS, pH 7.4)
Extinction Coefficient, ε(λmax): 75,000 M-1cm-1 (photoactivated, PBS, pH 7.4)
Fluorescence Maximum, λfl: 615 nm (photoactivated, PBS, pH 7.4)
Photoactivation Wavelength:360 - 440 nm
Recommended STED Wavelength, λSTED: 685 −715 nm
Fluorescence Quantum Yield, η: 0.80 (after photoactivation, PBS, pH 7.47)

Localization microscopy can image nanoscale cellular details. To address biological questions, the ability to distinguish multiple molecular species simultaneously is invaluable. Here, we present a new version of fluorescence photoactivation localization microscopy (FPALM) which detects the emission spectrum of each
