Re: [Histonet] Improved Eosin
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.
