FluoroQuest™ Anti-fading Kit I *Optimized for Slide Imaging*

FluoroQuest™ Anti-fading Kit I

Optimized for Slide Imaging

When exposed to excitation light, fluorescence intensity of dyes decreases due to their photooxidation or other photoreactions. There are very few fluorescent dyes that completely resist photobleaching. Frequently, when a section has been scanned repeatedly under strong excitation light, dyes could lose significant fluorescence signal before visual evaluation or photography can be accomplished. For examples, the photobleaching of fluoresceins (such as FITC-labeled antibodies) has become a major problem in fluorescence microscopy. In severe cases (such as phycoprotein-labeled bioconjugates), a fluorescence image of high resolution can not even be taken due to the extremely high photobleaching rate. Fluoroquest™ Anti-Fading Kit is to reduce the dye photobleaching rate, giving researchers longer observation time. The kit contains all the essential components that can be readily applied to imaging experiments. They are all premixed and ready-to-use solutions. This kit is designed for slide format while #20003 is designed for microplate format.

U2OS cells in a 96-well Costar black plate were loaded with 1 µM calcein, AM for 1 hour, fixing with 2% formaldehyde for 30 minutes. Anti-fading reagents were added to the samples after removing all the media. The FITC signals were compared at 0 and 30 seconds exposure time by using an Olympus fluorescence microscopy. The same exposure settings were used for all the images.
