Thanks for the replies :)
I did have a search on Pubmed before I started all this but was not able to
find either any consistent protocols or any decent photographs. I would be
very grateful if you could sen d me your protocol for NADPH-d staining. The
brainstems are very old formalin fixed tissue which I have cryoprotected and
sectioned to 50um. They have been stored in the cold in PBS since then -
about a month. One more question i have is that, now I have stained them or
maybe overstained them, is there a way of removing the stain that is there,
eg, with alcohol or something like that.
