Hi Sarah,
I think the Orcein-method for elastica would work with Osmium.

Just try it,
Joachim

Betreff: Osmium for Fat/VVG/TRI


Dear Netters,
   Had a researcher come in yesterday wanting to do an elastic stain (VVG),
collagen stain (Trichrome) and a fat stain (Osmium Tetroxide for fat, AFIP
manual, page 143) on the digital cushion of the horse hoof.  My question is
can the VVG and the Trichrome be done on the same tissue as the osmium
treated tissue or will he have to submit separate tissues, ie. one for the
osmium pre treatment and another for the connective tissue stains?  They
would prefer the same tissue since they are trying to do a 3D computer
model.   I was wondering, could the osmium be removed with hydrogen peroxide
after sectioning and then proceed with the connective tissue stains?
Thanks, Sarah
