Sharon:

Here is a picro-sirius red stain thread from Histonet.  Hope it helps.

Histonetters,
  I need some help recovering a stain for osteo components which one of my
pathologists swears is a "commonly-done" stain.  He thought it is called a
pico-sirius red...   Anyone know of a reference/recipe?

I use this stain for calcified bone.  It is 0.2% Sirrus Red made up in
saturated picric acid.  Stain sections for 20 min. then rinse several times
and let sit in dh20 for about 5 min. to remove the
yellow picric background.  This stain can be reused for 30 days and should
not be filtered.  It stains calcified bone red, nothing else stains.  It is
a good substitute for a silver von kossa stain.

Picro-sirius red is a used as a selective identification of collagen in bone
and soft tissue, and can be viewed with polarization.

I had private communication with Junqueira about technic, anwashing after
the Picro-Sirius stain, he used running tap water wash until no color comes
out.  If your water is highly alkaline, he suggested using a slightly
acified water.  He also used fresh hematoxylin, no more than 2 months old
for best results.

Staining method was:

0.1% sirius red in saturated picric acid for 1 hour,
rapid wash in tap water
fresh Harris hematosylin for 6min.

Happy staining!

Hi Sue. Picro-Sirius red is a connective tissue stain. It does not stain
"BONE" per se but rather, it stains the bone collagen ( likely type I) which
forms first (coarsely fibered or woven bone commonly called osteoid)  and
then becomes mineral-laden (hydroxyapatite which is composed of calcium,
phosphate and hydroxyl ions). It was described very nicely by Holde Puchtler
in  "Manual of Published Histochemical Methods" by Holde in 1980. It is also
in Theory and
Practice of Histological Techniques by Bancroft and Stevens1996.

Hi Mary

Our paediatric pathology lab routinely does elastic picro sirius red
instead of EVGs because one of the paediatric pathologists is colour blind
and finds EPSRs easier to interpret.

You can find our method at;

Hope this is of some help.

Cheers

Does anyone have a procedure for picosirius red stain for collagen?

thanks,
