Biomount Tissue Mounting Media 100ml,
Biomount™ reduces fading of immunogold/silver signals in sections on glass slides. It is suitable for both resin and wax embedded tissue sections.
Some mounting media oxidize rapidly on exposure to air, forming carboxyl groups. This may be especially so when sections have been cleared in a solution containing aldehyde groups. It is sometimes observed that the immunogold / silver stain fades after a few weeks, or even in a shorter time, from sections that have been mounted with these media under cover slips. The silver is still present, but has formed translucent silver carboxylate salts. Visibility can be retrieved by removing the cover slip and washing in xylene (xylol) and then immersing the slide in photographic developer, but this is a tedious procedure. Biomount prevents this fading because of its low oxidizing properties.
Biomount is miscible with xylene and may be applied to sections on slides in the no
