EMS Shield Mount is an aqueous non-permanent, low viscosity mounting medium for immunofluorescence and confocal microscopy. This unique formula prevents rapid photobleaching of FITC, Texas Red, AMCA, Cy2, Cy3, Cy5, Alexa fluoro 488, Alexa fluoro 594, Green fluorescent protein (GFP), tetramethyly rhodamine and Redox. The fluorescence is retained during storage at 4 degree C in the dark. This medium does not contain phenylenediamine, which destroys immunofluorescence of Cy dyes.
