Although it should NOT be the cause, I always used my cryostat at -20 to -25ºC Second I always warmed the slides (at least 30ºC) before picking the sections. This requires having a well extended cryosection and to pick them up with a "smooth movement". You will not have any chance of "rearranging-extending" the section. As a fixative I used NBF for 30 seconds → to regular or special staining. René J.

I used Leica cryostat previously but i never got these problems...Even i used non adhesive but sections still on the slides..Can someone advised please.Maybe youre using the same tissue tek cryo 3... _______________________________________________ Histonet mailing list Histonet@lists.utsouthwestern.edu http://lists.utsouthwestern.edu/mailman/listinfo/histonet _______________________________________________ Histonet mailing list Histonet@lists.utsouthwestern.edu http://lists.utsouthwestern.edu/mailman/listinfo/histonet
