Prussian Blue Iron Stain Kit is used for the histochemical demonstration of ferric iron and ferritin in tissue sections, blood smears, and bone marrow samples. The stain is based on the Perls’ Prussian Blue reaction, where ferric iron reacts with potassium ferrocyanide under acidic conditions to form ferric ferrocyanide, commonly known as Prussian Blue.
Synonyms and related names: Perls’ Prussian Blue stain, iron stain kit, ferric iron stain kit, ferritin histology stain.
This staining method is widely used in histology and pathology laboratories to identify iron accumulation and hemosiderin deposits in biological specimens. The reaction is considered a histochemical detection method rather than a traditional dye-based staining procedure.
Kit contents: 4% Potassium Ferrocyanide, 4% Hydrochloric Acid, and 1% Nuclear Fast Red counterstain.

Applications
Histology & Pathology
Prussian Blue staining is commonly used in histology laboratories to identify ferric iron accumulation and hemosiderin deposits within tissues.
Ferritin Detection
The Perls’ reaction allows visualization of ferritin-associated iron in biological specimens for diagnostic and research applications.
Bone Marrow & Blood Smears
The stain kit can be used with blood smears and bone marrow preparations to evaluate iron storage and iron-related abnormalities.
Tissue Iron Studies
Researchers use Prussian Blue staining in studies involving iron metabolism, iron overload, and tissue iron localization.
Fixation & Compatibility
- 10% neutral buffered formalin (NBF) or alcohol fixation may be used
- Recommended for tissue sections approximately 4–5 µm thick
- Compatible with standard histology sample preparation workflows
- Suitable for paraffin-embedded tissue specimens
Final staining intensity and visualization may vary depending on fixation conditions, specimen preparation, and staining protocol parameters.
