[Histonet] toluidine blue

[Fred Underwood]

I use a 0.5% toluidine blue in 0.5NHCl (90ml. DH2O, 4.2ml conc. HCl) for
30 minutes.  Rapidly dehydrate in 3 changes of absolute alcohol, xylene,
and coverslip.  A section of skin works good for control.

I was wondering if anyone had any tips for controls and procedures for
the toluidine blue stain for mast cells.  I am not seeing any
differentiation in my stain.
Thanks.
