[Histonet] Alternatives to Weigert's Iron Hematoxylin for Mucin andTrichrom e Staining

[Tony Henwood]

You could try the celestine blue-haematoxylin sequence:
This method uses a Modified Harris's haematoxylin but any alum haematoxylin (routinely used in your H&E staining) should work.
Document Procedure:	
The Celestine Blue - Alum Haematoxylin Procedure

Principle:	
Celestine blue resists acid decolourisation and the ferric salt included acts as an additional mordant for the Haematoxylin to provide a reasonably acid resistant nuclear stain.	

Fixation:      10% buffered formalin.
Microtomy:     paraffin sections at 5µm.

Reagents: 	
1.	Celestine Blue Solution:
		0.5% Celestine Blue (CI 51050) in 
		5% iron alum (ferric ammonium sulphate).

2.   Harris's Haematoxylin Solution.

Procedure:
1.	Deparaffinise and take sections to water.
2.	Celestine blue solution, 5 minutes.
3.	Rinse in tap water.
4.	Harris's Haematoxylin solution, 5 minutes.
5.	Wash in water.
6.	Differentiate in acid alcohol, as necessary.
7.	Wash in water.
8.	Blue in blueing solution.
9.	Wash in water.
10.	Rinse in distilled water.
11.	Proceed with required staining technique.

Importance: High


 Hello All:

Can anyone suggest an alternative to Weigert's Iron Hematoxylin for nuclei staining with Mucin and Trichrome protocols? I have some standard hematoxylin (7211) that I will be using for my routine staining. However, with the shortage, Weigerts is on backorder until October.
