Fluoro-KEEPER Antifade Reagent offers increased resistance to photobleaching of various fluorescent dyes.

Cells stained by each fluorescent dye were mounted in Fluoro-KEEPER Antifade Reagent, 85% Glycerol containing PBS as a control. Samples were illuminated for 60 seconds. Each number indicates fluorescence intensity as percentage of initial intensity after 60 seconds exposure photobleaching.

1. Remove excess liquid from a slide and dispense a couple of drops of the product onto a specimen.
2. Cover the specimen with a coverslip.
3. The slide can be observed immediately.
4. To obtain sufficient counterstain, incubate the slide for 30 min. at room temperature protecting from light. For long-term storage, sealing with hot wax or nail polish and store at 4°C protected from light.

Precaution

• Because the product contains glycerol, it is not recommended for the detection of phycobiliproteins such as phycoerythrin and alloophycocyanin.
• Refractive index of Fluoro-KEEPER Antifade Reagent with DAPI and without DAPI is 1.43 - 1.44(20°C)
