We have been doing a PAS stain on the same control block and same
reagent supplier for a long time.  
Yesterday when we ran the slides, they failed to stain
We opened new bottles of Periodic Acid and Schiff's Reagent and recut
fresh controls
Still, we are unable to get any staining.
Suggestions to help would be appreciated
