Bouin fixative

Bou·in fix·a·tive

(bū-an[h]'),
a solution of glacial acetic acid, formalin, and picric acid; useful for soft and delicate tissues (as those of embryos) and small pieces of tissues; it preserves glycogen and nuclei and permits brilliant staining, but penetrates slowly, distorts kidney tissue and mitochondria, and does not permit Feulgen stain for DNA.
