[Histonet] Re: Weigert's Iron Hematoxylin

[Johnson, Nacaela]

Iron hematoxylin is more resistant to decolorization than aluminum
hematoxylin.  Since there are so many acid steps that follow the
hematoxylin, it is wise to use the Weigert's so you do not have to worry
about decolorizing the other tissue elements too far.  However, if you
optimize your stain to the use of the Gill's and the pathologists agree
that staining intensity is optimal then it should be fine.  I wouldn't
do it without optimizing first.  So overall, the two are not exactly
interchangeable since some of the subsequent staining steps may have to
be altered.

Hi Histonetters,

 

I have a quick question regarding Weigert's Iron Hematoxylin and Gill's
3 Hematoxylin. One of the guys here thinks that we can interchange these
2 stains. I am attempting to perform a Masson Trichrome stain and it
calls for Weigert's Iron Hematoxylin. This person in my lab says to just
use Gill's Hematoxylin in place of the Weigert's stain. Is this right?

 

Thanks for your help

 

Kimberly
