Citifluor
The use of fluorescent labels and markers is widespread and immunofluorescence, 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 is also a problem when trying to visualise materials having a low level of labelling. The photofading of labelled materials can be retarded by the use of the Citifluor mountants. They are also useful for rhodamine and DAPI.
The antifadent solutions AF1, 2 and 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 n-propyl gallate, which is particularly suitable for use with DAPI and Alexa dye-stained materials, as well as FITC-labelled materials

AF4
Glycerol solution containing n-propyl gallate for use with labelled tissue sections and dead cells. An aqueous solution (75% AF4 and 25% water) has a pH of 5.
Cultures of purified cortical astrocytes with rabbit antisera against glial fibrillary acidic protein, a component of the astrocyte cytoskeleton. The rabbit antisera was visualised using fluorescein-conjugated sheep anti-rabbit 1 g antisera. Micrographs courtesy of Mark Noble, Institute of Neurology, London.
The first visual shows fluorescent using glycerol as the mountant media
The second visual shows fluorescent using Citifluor (Glycerol/PBS) as the mountant media

This Citifluor non-fluorescent immersion oil contains antifadent AF87.
It is designed for use at high magnifications.
It is particularly suitable for preventing the fading of dyes such as DAPI which have the unfortunate tendency to disperse in glycerol-based mounting solutions.

Citifluor also provides a solid mountant.
It is supplied as a two-component pack comprising:
- PVA solution. 25ml
- Citifluor antifadent in buffer (AF100). 5ml
The components can be mixed as required, applied to the specimen and allowed to dry to give a clear film.

The CFM solutions have been specially formulated to have a refractive index of 1.52 (similar to glass), so that effects of refraction on image quality are minimised. They are particularly useful for high magnification work and may also be used as immersion oils. They are valuable for laser scanning microscopy where three dimensional imaging of specimens is carried out. CFM solutions should only be used with fixed (cross-linked) samples.
CFM 1.
Glycerol phosphate buffered saline solution. Available in two sizes.
CFM 1 plus antifadent.
Glycerol phosphate buffered saline solution containing antifadent. Available in two sizes.
CFM 2.
Glycerol tris buffered solution. Available in two sizes.
CFM 3.
Glycerol phosphate based solution containing antifadent. Available in two sizes.

UV mountants harden to give a clear film when exposed to light. They fix the specimen upon hardening, making microscopic examination of specimens that move around or change shape on the slide much easier.
The solutions are water miscible prior to curing and so can be used with non-dried specimens.
