[Histonet] Can Alk phs be run on peroxidase slides?

[Dana Settembre]

Hi,
One of my pathologists is asking if I can take a slide that has already
been stained with a
peroxidase/avidin/biotin/DAB detection system and re-stain with an
Alkaline Phosphotase detection system.
Can it work?
Must it be de-stained?

Any info will help.  Thanks,
