Perls reaction
Web12. jún 2003 · The Prussian blue reaction of the Perls method depends on the production of insoluble precipitate when ferrocyanide ions, [Fe II (CN) 6] 4−, react with Fe 3+ liberated in acidic solution. The insoluble blue reaction product of the Turnbull method is formed by reaction of ferricyanide ions, [Fe III (CN) 6] 3−, with Fe 2+. WebPerls’ reaction, Left: x20. Right: glioma x40. Moreover, we deal with the realization of animal experiments for monitoring of cognitive functions, such as: Morris water maze, the open field test, the light/dark preference test, the elevated plus maze test, the forced swim test and the social interaction test.

WebThe Perls’ reaction was negative. In the muscles of the right thigh, iron-oxide-containing structures resembling dark blue conglomerates were observed (Figure 2A). A detailed examination showed that Fe 3 O 4-OA-NP was localised intracellularly. Cells containing Fe 3 O 4-OA-NP were present among tissue phagocytes.
