Dissolve the ferric ammonium sulphate in the distilled water.
Add the celestine blue B. Boil for 5 minutes. Cool and filter.
5µ paraffin sections of neutral buffered formalin fixed tissue are suitable.
Other fixatives are likely to be satisfactory.
Bring sections to water via xylene and ethanol.
Place into the iron alum-celestine blue solution for 3 minutes to 2 hours.
Wash with tap water.
Counterstain with eosin or other counterstain.
Dehydrate with 95% and absolute ethanols.
Clear with xylene and mount with a resinous medium.
Nuclei – blue
Cytoplasm – pink
The iron alum-celestine blue solution is stable for a few months.
A staining time of 5-10 minutes is usually satisfactory for formalin fixed tissues.
This method has been recommended as a substitute for Hematoxylin and Eosin.
Proescher and Arkush also recommended the dyes gallamine blue
and gallocyanin. Neither dye is as stable as celestine blue, although the
colour with gallocyanin most closely resembles alum hematoxylin of all three dyes.
