Hi John!
That used to happen to me and I changed all of my slides to + charged slides and it stopped. Now, I put the sectioned slides directly into Hematoxylin for staining, but I have had techs feel more comfortable putting them in 95% Alcohol first to fix. I personally haven't had negative or positive feedback on the stain quality either way (my Pathologists didn't notice a difference). 
I also heard just yesterday from a tech that she puts them into Formalin before staining...this I have never heard before, but she claims it works. 
Good luck, hope this helped a tad...
Kari :)

Subject: [Histonet] tissue coming off slides


Hi All,  A group I work with just came to ask if there was a way of 
keeping frozen tissue sections from coming off a slide?  It seems there 
technician used uncoated/regular slides to mount 100's of sections.  
The tissues were embedded in OCT and cut at 5 microns but of course are 
sliding off during any staining procedure.  Is there a protocol of any 
sort to coat the slides after the fact to retain the sections through 
staining?  I at least suggested they stain flat.  Any suggestions are 
appreciated.  John
