The TB/AY stain is also known as the "rapid staining method". We buy the kit 
from Poly Scientific (and I know that they will send you a copy of the 
staining method of you call them.) A quick run down of the stain below is 
done by flooding the slides on a rack except for the last part.

1.Periodic acid 1% aqueous - 10 min.
2.Rinse in tap water
3.Sodium metabisulfite 5% aqueous - 5 min.
4.Rinse in tap water for 2 min.
5.Alcian yellow 1% - 5 min.
6.Rinse with tap water
7.Stain in a coplin jar in freshly prepared Tol. blue working solution (see 
below) for 3 min.
8.Rinse well in tap water
9.Blot slides dry, dehydrate quickly, clear and mount

Working Toluidine Blue:
50 ml distilled water
0.5 ml of stock 1% Toluidine blue aqueous
2 drops 3% Sodium hydroxide aqueous

Heliobacter pylori - blue
Mucin - yellow
Background - pale blue

A personal note: I don't know what the Alcian yellow from Poly Scientific is 
mixed with - water???  We were for a time making up most of our solutions, 
except for the alcian yellow and the toluidine blue, but the kit isn't that 
expensive and you really don't go through too much solution when you're 
dropping it directly on the slide.  Also, during dehyration we do 
95%,100%,100% just several dips each as this is where differentiation takes 
place.

In the April 1999 issue of "Histo-Logic" several methods of H. pylori 
staining technics were compared and the "Rapid" method came out on top.
