WEIRD FIXATIVE

From:Andrea Grantham

One of the research techs here brought some tumor tissue to the lab fixed 
in Copper Formalin.
In one of his replys to my quizzing him about the fixative he said that he 
wanted to make up zinc formalin but didn't have any zinc and "copper is 
right next to zinc" (on the chart, I presume) so he just thought he'd give 
it a try.
What might we expect in terms of staining?
When we bisected the tumors to process it was interesting to see that there 
was a turquoise color in the center of the tissue. None of the other tumors 
fixed in other fixatives  (10% NBF, Carnoys) had this color.
