Did you know?
WebStains used for the identification of elastic fibers were the traditional Taenzer-Unna orcein (36) and the more selective orcinol-new fuchsin (37). Aldehydes were detected histochemically by the application of Schiff's reagent which had been prepared by the cold method (36). In all experiments, comparable sections from experimental and control ... WebIt was demonstrated on formalin fixed tissues that orcein reactivity is not prevented by measures which block carboxyl, hydroxyl, amine or aldehyde groups when it combines with collacin and elastic tissue, and that collagen, ordinarily unreactive, reacts strongly when these polar groups are blocked. Using the Taenzer-Unna acid orcein method of staining, it …
