Is xylene a mounting medium?

Because slides are usually mounted from xylene, xylene should be the solvent for the mounting media. Toluene is more volatile than xylene so bubbles are more likely to appear. Reflective index of the mounting media is also very important.

What is DPX mounting medium?

The dried resin is freely soluble in xylene and other organic solvents. The standard mountant for histology and also for taxonomy, be it zoological or botanical is Canada balsam, a now scarce and very expensive natural resin. [1], [7]

When to use aqueous mounting media in histology?

Aqueous mounting media are used when dehydrating and clearing will adversely affect the stain. They can be classified for use in histology as simple syrups, gum arabic media, and glycerol gelatins. Both gum arabic and glycerol gelatins media cause, or allow diffusion of basic aniline dyes into the surrounding medium.
