Mast cell granules of some species are dissolved by aqueous
fixatives. Alcoholic mixtures (e.g. Carnoy or an alcoholic
Bouin) are OK for any species. The best reference for all this
is quite old but very good: Hans Selye's book "The Mast Cells"
Butterworths, 1963. Rat & mouse mast cells can be fixed with
aqueous mixtures like neutral formalin.
