RE: Safran du Gatinais
|From:||"Monson, Frederick C." |
Safran du Gatinais = Saffron of Gatinais
Saffron (Roboz)(C.I. #75100)* 6g (about 1/4 oz) (stigmas or
powder, I bet!)
100% Ethanol 100ml
saffron in EtOH in air-tight brown bottle*** (125ml serum
bottle with Teflon-lined screw cap)
leave at 56-58oC for 48hr**
stain for 15min in screw-cap Coplin jar (this is a last
The above came out of S.W. Thompson's, Selected Histochemical and
Histopathological Methods, Thomas, Springfield, IL, 1966, p 827-828 (Movat's
The web is wonderful!!!
A reference to a method/protocol contact for Movat's Penta-stain
came from Steve Slap at:
* Listed in Lillie's, "Conn's biological Stains", don't know about the new
edition soon to come.
** This is quite obviously an extraction performed on stamens (called
"saffron threads") or powder. You could presume that C.I. 75100 is a
purified powder from a similar organic extraction.
*** I always keep a quart can of black paint in my lab in which I dip small
bottles that I wish to make light tight. There is a plastic coating which
is available at Home Depot that comes in other colors
Saffron can be purchased in original form or as a powder as explained here:
A general link library for dyes (as in textiles!! where it all started) can
be found here:
Saffron is expensive ($36/oz) for cooking and exorbitant for staining at:
http://www.voigtglobal.com/cdi.htm (search )
So, after all of the intelligent stuff listed above, the search finally
produced a summary in a PDF file from Luna's " "Histo-Logic" at:
http://188.8.131.52/sakura/pdf/2n20472.pdf. He not only gave a
modified version of Movat but also the original source. Movat(1955),
A.M.A., Arch Path, 60:289-294 (which is also in Thompson's book).
We (Mom and I) have a snitched (rescued?) mortar and pestle to grind the
"threads" to powder for cooking. Only a little powder is required for
non-chef-like cooking, so the mortar and pestle hang out in the cupboard
most of the time.
Hope this helps, it was a nice exercise to start the day for me,
