Jo Dee,
Are you using a cryogun?  That could be a cultprit.  Also, are putting the slides directly into your fixative?  What kind of stainer are you using?  If your using a chain, put it in the heated section for 5 to 30 seconds.  I used to have this problem and when we put it in the heated section for just a few seconds>30sec that solved the problem.  OR you could have a bad lot of slides.

Hello histonetters,

I am cryosectioning unfixed fresh frozen spleens and when they are 
sectioned I can see a billion bubbles under the section.  Can anyone 
explain-

1.  What is happening?
2.  How can I avoid them?
3.  Is there a fixation procedure that can help?

The sections are falling off of the slide during staining.
Thank you for your help,
Jo Dee
