Dear me, I wouldn't want anyone to think that either, AND I am one of the
sites using them. When Richard Allen talked of removing Hematoxylin 7211
from the market, I was one of the techs kicking and screaming to keep it

I'm desperate to find a solution to the problem tho and will review

		Laurie Colbert  wondered, "Is Richard Allan a common
	with everyone who is having problems?????"
		My thoughts on this - I have used Richard-Allan hematoxylin,
	clarifier, bluing, and cytology stains practically since their
arrival in
	the marketplace (late '70's - mid-eighties?).  The ONLY consistent,
	reliable procedure I've NEVER had to "tweak" in the last 20 years
has been
	my H &E stain - as it is beautiful!  In fact, in 1990, when I was
	introduced to the gentleman (Jerry Fredenburg) who was responsible
for the
	development of these wonderful chemicals I immediately hugged him
and said,
	"Thank You, Thank You, Thank You!"  In fact, all of our area labs
have used
	these stains with great results.
		Now, in all fairness, I must add that I use real Xylenes for
	clearing and graded ethanols for dehydration.  Have not been seen
	consistent results with substitutes.
		And, as a final note, I remember thinking that the original
	question that started this query had a processing procedure that
	straight from formalin to 100%alcohol.  Isn't this a little odd?
	everyone use graded alcohols?
		Oh, well...I just didn't want techs, who've never used them,
to get
	the wrong impression about Richard-Allan stains.
