[Histonet] Improved Eosin

[edmondsj]

John,
I have a Johns Hopkins eosin recipe, it is as follows:

Ingredients:
Eosin Y  18gms
Phloxine B  7.5gms
Biebrich Scarlet  1.5gms
Distilled Water  2850 ml
Absolute Alcohol  750 ml

Procedure:
1: Dissolve all the dyes in the distilled water.
2: Add the absolute alcohol and continue stirring for at least 1
   hour.
This will make up a volume of 3610 ml, I add about two or three drops of 
glacial acetic acid to a 500 ml volume before staining tissue (this 
enhances the stain), you may not like the intensity but you can omit the 
acetic acid if you like.  I hope this is helpful to you.
