[Histonet] PTAH Mordant

[lpwenk <@t> sbcglobal.net]

We use Bouin fixative - 60 degree oven for 1 hour (after deparaffinizing
slides and running them down to water). (Can skip the Lugolizing steps)

Then wash in running water until yellow disappears from the tissue (1-10
minutes, depending on type of tissue. The more striated muscle there is, the
longer it takes.)

Then stain as usual in PTAH.

We get better, more consistent staining with this method. One of my fellow
students found it when we were in training. We had to do a PTAH for our
practical. Worked great. I believe it was from the Ann Preece book.
