I am not sure whose Haematoxylin this is, but we have used it extensively for many years for all trichrome stains. The recipe is is Bancroft & Stevens, should you need the ref.
Stable Iron Haematoxylin:
1g haem powder
100ml 95% alcohol.
Stir until powder is dissolved
10g Aluminium Chloride(hydrated)[AlCl3.6h2O)
10g Ferrous Sulphate(hydrated)
100ml Dist Water
Stir until dissolved and add Soln A & B together. Then add:
2ml conc HCl
2ml 9% Na Iodate
Mix & allow to stand at RT 48hrs before use. Soln remains stable at 4deg C for 2 months.
Staining time 10 mins, rinse in water and differentiate in 1min in acid alcohol if required.

Subject: [Histonet] hematoxylin
greetings. I would like to know if there is a substitute for the "celestine blue/hematoxylin" staining of nucleus that can resist a posterior acidic counterstain. I need to apply a protocol that uses this nuclear staining method but I dont have celestine blue and the company that suplies it says that it would last 2 months to supply the stain
Thanks in advance
