You will still get bubbles, just on the underneath if you put the sections on the coverslip.

I put the coverslip flat on kimwipe, then a dot of moutant on the coverslip (you really need to play with the right amount for your application), then wet the moutant with a drop of liquid (either xylene based or PBS, again depending on application), then flip the slide and catch the drop on the slide and let capillary action do the rest.

You can push out small bubbles, but use a tool, not your greasy fingers or moutant smeared gloves, I use a metal probe.

I then wick up the excess with a kimwipe on the edge of the slide

Important! Don't keep smearing the moutant, just start again if it looks like a mess.

Remember smears are the enemy of good imaging!

Hi Erika,
             If you have access to a plasma cleaner putting your slides
with sections in a plasma for 30 sec or so just before mounting makes
the slides and sections super hydrophyllic and the mounting medium wets
a treat. I found this trick quite helpful for minimizing bubbles, esp
those that love to form right over the section. Hope this helps. Tobias

Do you or your histology core mount tissues directly onto the coverslips? Do you charge or coat the coverslips so the tissue section can stick better for staining?
