Most Mast cells stain metachromatically, so a toluidine blue (0.1%
aqueous) will do the trick. Allow stained sections to air dry prior
to coverllipping (ie no alcohol). Churukian has a marvelous technique
that was published some time ago in J Histotechnology.
Aqueous alcian blue (1% in 0.5% HCl) (pH 1) will also stain them.
This is mainly due to their being rich in heparin sulphate. Try one
of the Sigma dyes - they tend to dissolve better at this pH.
My histonet summaries contain a page on Mast cell controls which may
be of use.
Regards, Tony
