You wouldn't expect acridine orange to stain lysosomes
in fixed tissue, though it has been used for that purpose
with living cells (Manyonda,IT & Choy,MY 1999 J. Soc.
Gynec. Invest. 6:158-166). A traditional histochemical
method for acid phosphatase activity should do the job
for lightly fixed material, and you'll have the added
advantage of a permanent preparation.
