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
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
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.
