Altmann's acid fuchsin picric acid is a histological stain for mitochondria.

It requres the tissue to be fixed in a non-acid dichromate fixative, then 
post-chromed for some time.  The tissue is then processed by paraffin and 
sectioned.

Staining is in aniline water saturated with acid fuchsin, which is applied 
much like carbol fuchsin in a ZN, i.e. heated.  Diffeerentiation is with 
picric acid.

The method requires considerable skill from the technologist, but produces 
red mitochondria on a yellow background.

I suggest that if you just want to demonstrate mitochondria, do a succinate 
dehydrogenase instead, it is much easier and much faster.

If you want, I can look up the details and send them on, but I recall they 
used to be in Culling's book.
