Permanent Mounting Media (Non-Aqueous)



Museum quality mounting media, permanent clarity, stringently controlled optical specifications

Histomount is the classic choice in synthetic mounting media. Histomount provides a permanent seal to store or ship slides with confidence.

Histomount is a pH neutral, UV stabilized preparation which retains its clarity and brilliance for years. Refractive index is matched to glass cover slips and slides, reducing chromatic aberration with any light source.

Histomount is effective with most clearing agents when used as a liquid cover slip or as a permanent mounting medium for traditional glass cover slipping. A dip stick providing an optimal amount of Histomount is provided with each 100ml bottle.

Citifluor Antifadent Solutions

Citifluor provides a range of antifadent mounting media which greatly reduces the fading of the fluorescence from FITC, rhodamine, Hoechst, Alexa, Green Fluorescent Protein, cyanine dyes, Texas Red, and phycoerythins. A range of antifadent mountants are available in either glycerol based or glycerol free solutions. Citifluor mountant can either be permanent (hardening) or not (non-hardening) depending on your labeling requirements.

citifluor mountant media citifluor mountant media

citifluor fluorescent antifade mounting medium The use of fluorescent labels and markers is now widespread and immuno-fluorescence, which relies on the use of antibodies tagged with labels such as fluorescein, is a well-established technique.

A common problem associated with the microscopical examination of these materials is that the illumination used for stimulating the fluorescence also causes degradation of the label and this causes fading of fluorescence. This also is a problem when trying to visualize materials having a low level of labeling. The photofading of labeled materials can be retarded by the use of the Citifluor mountants.

Antifadent (AF) Solutions
The antifadent solutions AF-1, AF-2 and AF-3 were specifically developed for use with FITC polyclonal antibodies but their use is now far more widespread. They show improved signal preservation with many other fluorochromes including rhodamines and DAPI. AF4 contains the antifadent propyl gallate, which is particularly suitable for use with DAPI and Alexa dye-stained materials, as well as FITC-labelled materials.

AF-1 - Glycerol-phosphate buffered solution containing antifadent for use with labeled tissue and dead cells. Available in two sizes.
