Red face H& E staining



Hi,
Brain sections (20-40 microns) are falling off from Fisher charged slides at post-fixing step with 10% formalin itself or/and with increasing % of water at rehydration during H& E staining. They are being stained 2-3 hours after cutting the brain.
Does anyone have ideas of what could be going wrong and how it could be prevented?
Thanks!

@shmily 10 Hi frozen sections have this problem if they are stored for a long time
Cryosections are only for temporary use for better images always go for formalin fixed paraffin sections
