Re: Copper Stain
|From:||Greg Dobbin <dobbin@Upei.CA>|
There a few to choose from. The rhodanine stain is quite nice (esp
in publication prints) but it is an overnight stain. More often lately, I
have been using Timm's Copper Stain.
I am no expert, but I am told that there are two forms of Cu stored in
cells, cuprous and cupric, one form in the nuclei (I forget which) and
the other in the cytoplasm. And it has been suggested that the
rhodanine stain only stains the cytoplasmic form (probably sufficient
information for diagnostic purposes), whereas Timm's Cu stain,
stains both forms (nuclear and cytoplasmic), more critical in copper
A third is Rubeanic Acid Method for copper, which I know nothing
about, but found the method in "Carleton's Histological Technique".
The Rhodanine method is in the AFIP "Methods in Histotechnology".
The Timm's method for copper is in an older text, (1970)
"Diagnostic Histochemistry" , by Zugibe and Mosby.
If you need a copy of any of these faxed, let me know.
