Abberior^®CAGE 590, NHS-ester

产品说明

一般描述

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

• First CAGE dye in the red fluorescent range
• Ideal for PALM, STORM, GSDIM
• Well suited as 2nd STED color (after uncaging)
