Re: ? about Bouins fixative
|From:||Barry Rittman <firstname.lastname@example.org>|
there will be some differences with staining.
Bouin's fixation, because of the picric acid, is a coarse precipitant
of proteins so that nuclei will look a little clearer as the nucleic
acids often have a clumped appearance.
When you fix in NBF and then post fix either the block or the sections
before staining, your greatest difference compared to NBF alone will be
that the connective tissues will stain more brilliantly in trichromes
As far as elastin staining goes, I did not notice much difference except
for the differences in degree of shrinkage in tissue as a whole.
I have told my wife that you instructed us all to have a great weekend
and this meant no house cleaning!
Hope you have a really nice weekend.
