Ken, if you can't help, don't give meaningless advice.
To the original poster: can you cryoprotect your tissue using a 30%
sucrose solution? Or try another fix technique such as acetone or
In the end I suspect a cryostat is going to be your best bet - it
doesn't require fixation and is almost guaranteed to pull off a clean
section which can be air-dried to fix it to the slide.
