Try manually coating plain glass slides with poly-l-lysine, 
chrome/gelatin, or glycerin/gelatin.  We use all of these for our thin 
plastic sections.  I also suggest setioning a micron or two thinner (cut 
at 3 or 4um).  A thinner section will reduce the surface area to volume 
ratio and may promote better section adherance.  You may need to dry the 
sldies using a slide press and dry longer or with higher temperatures. 
Also, try searching the Histonet archives for alternative slide coating 
suggestions.  Good luck!

Help!  We are losing our thin plastic sections!  We have cut PMMA
plastic sections at 5 microns and put them on "+" slides, and the
sections fall off either during de-plasticizing or during staining!  We
have tried:  Haupt's adhesive, longer drying times, "+" slides, plus
slides and Haupt's together, etc....no luck!  Any suggestions would be
