An older method of inhibiting endogenous alkaline 
phosphatase is to treat the section with Lugol's or 
Gram's iodine solution. Obviously not highly
specific, but does that matter for your purposes?

According to Humason's Animal Tissue Techniques,
alkaline phosphatase can also be inhibited by EDTA,
formaldehyde, KMnO4, cysteine or sodium arsenate.
