Hi Cheryl and Histonetters,

Very early in my career, we did this very same stain (that we called
HBFP) mostly on autopsy cases to rule out myocardial infarction.  But it
was clear to me right away that one could determine the outcome of the
stain be how and how long one differentiated the slides.  In essence,
you could make it turn out positive or negative!

I talked to the person(s) at Mayo that developed the stain and they were
quite closed mouthed about the whole thing and ultimately told me they
were not standing behind their stain anymore for the very reason I

Now, this was in the mid 70's so I don't know what's become of this
stain since though I don't know anyone these days doing it.

Cheryl, I don't know what your original question was, but I threw my 2
cents in anyway.
