Polysciences, Inc. Prussian Blue Iron Stain Kit (Reaction for Demonstration of Iron)

Prussian Blue or Perls reaction is used to demonstrate ferric iron and ferritin. This is not a true staining technique rather, it is a histochemical reaction. The protein is split off by the hydrochloric acid, allowing the potassium ferrocyanide to combine with the ferric iron. This forms the ferric ferrocyanide or Prussian Blue.
