[Histonet] RED COUNTERSTAINS

[Mark Tarango]

I like using Richard-Allen's 7211 hematoxylin for counterstains like in the
iron stain.  I do a minute w/ hematoxylin, rinse, and then a minute in their
clarifier II.  If you use distilled water the hematoxylin stays red and
looks great.  If you have any lying around, it can't hurt to try.
