Re: alternate stain for b & b

From:Nancy E Weber

Hi Jerry, Here's a Brown and Hopps that I've used that works well.

Fixative:  10% neutral buffered formalin.
Technique:  Cut paraffin sections at 3 to 5 microns.
Quality Control:  Tissue containing both gram + and gram --  organisms.  (
We had one of our research microbiologists inoculate muscle tissue with both
organisms for us )

Staining Procedure:

1.  Deparaffinize and hydrate sections to distilled water.
2.  Flood slides with crystal violet for 2 min.
3.  Rinse in tap water.
4.  Flood slides with Gram's iodine for 5 min.
5.  Rinse in tap water.
6.  Blot one slide at a time with filter paper and decolorize quickly in
acetone.
7.  Rinse in tap water.
8. .Flood slides with working basic fuchsin for 5 min.
9.  Rinse in tap water.
10. Differentiate with Gallego's solution for 5 min.
11. Rinse in tap water and blot slides, but do not blot to dryness
12. Dip slides in acetone quickly three times.
13. Dip slides in picric acid-acetone quickly three times.
14. Dip slides in Acetone quickly three times.
15.  Dip slides in acetone-xylene quickly five times and clear with three
changes of xylene.
16.  Mount with xylene-based resin.
On steps 12 -15, I would set up a row of coplin jars with each solution and
take one slide at a time and go down the assembly line to the final xylene
jar.

Results:
   Gram positive bacteria................................Blue
   Gram negative bacteria.................................red
   Backround...............................................yellow
