Dear Martin
Your mail has drawn my attention. I am also interested to know if there is
any non-DAB method for COX staining. I expect that someone from histoland
may reply.
However, we were unable to get a good COX staining in frozen kidney tissue
(rat), may be due to excess endo peroxidase in kidney. Could you please
e-mail me your protocol?
(PS: I have seen your nice website, although in Deutsch.)
Best regards

Dear Histonet members,
staining of snap frozen muscle tissue for cytochrome oxidase (COX) using
diaminobenzidine (DAB) works nicely in our laboratory.
We would be happy to know, however, if anybody is aware of an
non-carcinogenic alternative method to visualize cytochrome oxidase
activity.
Thank you very much for your help
