[Histonet] collagen staining

[Lobke De Bels]

We also searched for a collagen staining with a good contrast for image
analysis. This is the protocol we use:

* biebrich scarlet-acid fushin solution (BS-AF)
   biebrich scarlet, aqueous 1% .... 90,0 ml
   acid fushin, aqueous 1%,......... 10,0 ml
   glacial acetic acid............... 1,0 ml

* phoshomolybdic-phosphotungstic acid solution (PMA-PTA)
   phoshomolybdic acid ................5,0 g
   phosphotungstic acid ...............5,0 g
   distilled water...................200,0 ml

* aniline blue solution (AB)
   aniline blue........................2,5 g
   glacial acetic acid.................2,0 ml
   distilled water....................100,0 ml

* 1% glacial acetic acid solution
   glacial acetic acid.................1,0 ml
   distilled water....................100,0 ml

staining procedure:
- deparaffinize and hydrate to distilled water
- BS/AF solution :3 X up and down
- rinse in distilled water
- PMA-PTA solution: 20 min
- AB solution: 8 min
- rinse in distilled water
- glacial acetic solution: 8 min
- dehydrate in alc 95%, isopropylalc, xyleen
- mount DPX

result:
collagen => blue
cytoplasm,keratin, muscle => red

you can also use weigert's iron hematoxyline (10min) for the nuclei, but for the
analysis it was better without for us.

good luck
