Well, I stand corrected! Never let it be said that I
don't admit when I am wrong. This was what was stated
to me. I always say, The mind is like a parachute,
keep it open!
By the way, the Alcian Blue pH 2.5/PAS from Biocare's
website still has the hematoxylin showing nicely.
That image was taken prior to incorporating any
stabalizers in the stains. I'm not sure if it is still
on the website. I know that several stain kits have
been eliminated, since I left. No $$ in it compared
to IHC. They no longer have ART Names for the kit's,
just the generic name.
Also, FYI--I don't get any residuals from Biocare.
