Anti-Fade Fluorescence Mounting Medium - Aqueous, Fluoroshield

Fluoroshield is an aqueous mounting medium for preserving fluorescence of tissue and cell smears. 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, Redox, phycoerythrin (R-PE), phyocyanin (PC), and allophycocyanin (APC). The fluorescence is retained during prolonged storage at 4oC in the dark. This medium does not contain phenylenediamine, which destroys immunofluorescence of Cy dyes, R-PE, PC and APC.

Procedure

1. Bring the vial to room temperature.
2. Rinse slide to be mounted with distilled or deionized, touch the edges of slide on a paper towel to remove excess water. Place slides on a flat surface.
3. Turn the vial upside down and open the dropper to remove any air bubbles.
4. Apply 3-4 drops of mounting medium directly on top of the specimen and spread out evenly by tilting slide back and forth or spread evenly with a 0.2 ml plastic pipette tip making sure the tissue is not touched. Excess medium can be removed by touching the edges of slide against paper towel.
5. Let stand at room temperature for about 5 minutes.
6. Apply cover slip carefully avoiding air bubbles.
7. The specimen is ready for visualization under a microscope.
8. One can seal the edges of cover slip with nail polish, any organic medium or our Organo mounting medium (Limonene Mounting Medium ab104141). If a coverslip is not sealed air bubbles will appear in few days.
9. For storage it is recommended that the slide be stored in the dark at 2-8°C.

Removal of Coverslip

Coverslip can be removed before sealing the edges. Soak slide in warm (37°C) distilled or deiononized water for several minutes. Carefully and slowly move the coverslip. Soak in water for an additional few minutes to remove coverslip. Rinse slide several times with warm water to remove all mounting medium. The slide can be remounted again.

Anti-Fade Fluorescence Mounting Medium ab104135 (previously called Fluoroshield Mounting Medium) is an aqueous mounting medium designed to preserve fluorescence when imaging tissues and cell samples.

The formulation prevents rapid photobleaching of FITC, Texas Red, AMCA, Cy2, Cy3, Cy5, Alexa Fluor^® 488, Alexa Fluor^® 594, Green fluorescent protein (GFP), tetramethyl rhodamine, R-Phycoerythrin (R-PE), Phycocyanin (PC), and Allophycocyanin (APC).

Fluorescence is retained during prolonged storage at 4°C in the dark. This medium does not contain phenylenediamine, which destroys immunofluorescence of Cy dyes, R-PE, PC and APC.

Mounting media products

For fluorescent cell and tissue staining, Abcam recommends this product (Fluorescence Mounting Medium ab104135), Mounting Medium with DAPI Mounting Medium With DAPI - Aqueous, Fluoroshield ab104139, and Mounting Medium with PI Mounting Medium With PI - Aqueous, Fluoroshield ab104129. For thick sections or tissues containing lots of fat, we recommend Glycerol Mounting Medium with DAPI Glycerol Mounting Medium - Anti-Fade with DAPI ab188804.
