Instructions for use
Hematoxylin solutions A and B acc. to Weigert
Art. No.: X906; X907
To get the working solution (iron hematoxylin solution) mix both solutions A and B at a ratio of 1:1 prior to use. The
working solution is stable for about 8 days at room temperature. It is used when an acidoresistant staining of nuclei is
required, e.g. when working with delimed tissues or for counterstaining during trichrome staining. Pure hematoxylin
stainings will fade under acid conditions after a time and, therefore, are not suitable.
Masson Goldner Trichrome Staining
A successive staining method with three different staining solutions allowing a differentiated visualisation of various
fibers of connective tissue against epithelial and muscle tissue.
Goldner’s stain I: Muscle tissue and cytoplasm red (ponceau), connective tissue also red (acid fuchsine)
Goldner’s stain II: Erythrocytes orange (orange G), connective tissue without colour (phosphotungstic acid)
Goldner’s stain III: Connective tissue green (light green SF)
Principle of staining:
The dyes differ in particle size: Goldner’s stain I contains a fine-particle phase (ponceau), which infiltrates quickly all
structures of tissue, and a coarse-particle phase (acid fuchsine), which works more slowly. At first it stains only the
coarse structures of tissue by masking the fine-particle phase. You have to stop the staining procedure at that point to
avoid an overstaining of the tissue.
During the differentiation step with Goldner’s stain II (phosphotungstic acid) it is important to decolour the connective
tissue as much as possible. Only then it can be stained with Goldner’s stain III (light green).
Additional chemicals required:
Goldner’s stain I (Ponceau-Fuchsine Art. No. 3469)
Goldner’s stain II (Phosphotungstic acid - Orange G, Art. No. 3470)
Goldner’s stain III (Light green SF yellowish, Art. No.3473)
Acetic acid solution 1% (Acetic acid 100%, Art. No.3738)
Instead of light green solution it is possible to use a
0.1-0.2% solution of anilinblue (Art. No. 4002) for
counterstaining (step 7).
Result:Cell nuclei: dark brown; Cytoplasm, muscle: red; Erythrocytes: orange; Connective tissue: green

Van Gieson Trichrome Staining
This staining method allows a differential visualisation of tissue structures in paraffin sections, especially the collagen
connective tissue.
Van Gieson’s solution contains two dyes with very different properties: The fine-particle picric acid
infiltrates quickly all structures of tissue by staining them yellow. The coarse-particle acid fuchsine can
stain only the coarse structures of collagen connective tissue during the short residence time. There
the picric acid is masked. Do not prolong the residence time to avoid the masking of picric acid in other tissue
structures, too (principle of progressive staining).
After staining remove the picric acid as completely as possible from collagen connective tissue for
tissue stained with acid fuchsine tends to fade out when being exposed to acids and bases.
The procedure demands some skill for you have to stop rinsing before the picric acid is also removed from the other
tissue structures (in that case the tissue becomes become reddish).
Cell nuclei: dark blue / dark brown
Collagene fibres: red
Muscle, cytoplasm: yellow

Please note at step 9:
Rinse moderately with highly concentrated ethanol
to remove the picric acid from the connective tissue
(see also above).

Elastica van Gieson Staining
Van Gieson trichrome staining is well combinable with elastica staining acc. to Weigert allowing a good overview of
various tissue structures, especially a differentiated visualisation of connective tissue and elastic fibres.
9. Rinse with distilled water
to avoid precipitation of hematein.
12. Rinse shortly with ethanol 70% and ethanol 96%.
Caution, picric acid is especially soluble in diluted
ethanol!
13. Dehydrate and rinse with ethanol 96%,
finish with 2 x ethanol 100%.
15. Mount with appropriate mounting medium.
Please note at step 13:
Rinse moderately with highly concentrated ethanol to
remove the picric acid from the connective tissue and,
therefore, avoid fading of the staining. Caution: If the
rinsing is too intensive the tissue becomes reddish!
Result:
Elastic fibres: dark violet
Cell nuclei: dark blue / dark brown
Collagene fibres: red
Muscle, cytoplasm: yellow
Please note:
The colour intensity depends on the pre-treatment and the composition of the samples to be stained.
It may initially be necessary to adapt the method to the respective conditions.
