I some experiences in immunochemistry, and tissues fixation, so
commercialy formaldhyde is not the best fixative existed. And
Bouin-Hollande is really bad, and if you can avoid to use it !
So paraformaldehyde fixative is is the most widely used fixative, either
with or without the addition of glutaraldehyde.
The paraformaldehyde concentration is between 1 to 4%, and high
glutaraldahyde concentration (>0,5%) increased structural preservation,
but also decreased the signal.
So try both fixatives alone or mixed and goog luck
