Hi,
What concentration of HCL are you using in solution B ?
is it 1% in the end, so i will have to use 3ml of the standard 36% HCL in
100ml, not just 1ml as mentioned in the protocols ?

------------------------------

*In general, we found the original/classic Weigerts iron hematoxylin stain to
be weak and almost washed out of tissues after staining with Massons
Trichrome. We no longer use the original formula, but a more concentrated
modified formulation that is not differentiated out as much by the acidifed
solutions found in Mass Tri.  We also found this problem with Massons
Trichrome kit components, where companies probably package the original
method's solutions.

We make up Weigerts fresh each time, and if it will last for a week for you,
fine......... but our work tends to be a one time staining with Mass Tri,
then weeks before it was done again.  The problem is: ferric chloride
continues to oxidize the hematoxylin throughout over time, that week or
longer, weakening the iron hematoxylin staining capabililty.   This is
discussed in Sheehan and Hrapchak Theory and Practice of Histotechnology.
Acid decalcified bone presents even more of a challenge, since nuclei
(DNA/RNA) in cells are hydrolyzed by acid decalcifiers, compromising
staining of nuclei, a problem seen with routine H&E staining.  Deanna was
correct on her assessment of this stain for best results.

This modified  Weigerts Hematoxylin was published in J of Histotechnology in
a paper on Kreybergs stain on skin.  The second Extra Strength Weigerts was
found on Histonet years ago and I have not tried the latter.  I suggest you
see which one you prefer, as we use the first Modified Weigerts.  Over the
years, the modified gave us far superior nuclear staining with Massons
Trichrome.

Weigert's Iron Hematoxyin MODIFIED (found in J of Histotechnology in a
method for Kreybergs stain on mouse skin).

Solution A.

            2% Hematoxylin in 95% ethanol

Solution B.

            62% Ferric Chloride   4 ml

            Distilled water           95 ml

            Hydrochloric acid      1 ml

Mix equal amounts of Solution A and Solution B

MIX FRESH JUST BEFORE USE AND DISCARD AFTER USE.

Extra Strength Weigerts Iron Hematoxylin from Histonet (reference unknown,
but supposedly from J of Histotechnology and method originated by Mabel
Myli, Mayo Clinic)

 Solution A:  Hematoxylin       10 g

                    95% ethanol      100 ml

Solution B:             11.6 g Ferric Chloride
                              980 ml Distilled water
                               10 ml 25% hydrochloric acid

Working Stain Solution
               Solution A                             5 ml
               Solution B                             25 ml
               Absolute Ethanol                  20 ml

Staining time for both of these formulations is 10 minutes, followed by
rinsing for 10 min in running tap water (hematoxylin will be black)

I do Weigert's staining for 10 minutes and use it for a week at the most.
I,
too, have heard conflicting times about the stability of the Weigert's, but
have
the best results with using it no longer than a week.
