HEMATOGNOST Fe™ staining kit for the detection of free ionic iron (Fe³⁺) in cells


Catalogue Number112084
DescriptionHEMATOGNOST Fe™
OverviewHEMATOGNOST Fe™ – staining kit for the detection of free ionic iron (Fe3+) in cells, is used for human-medical cell diagnosis and serves the purpose of the hematological and histological investigation of sample material of human origin. HEMATOGNOST Fe™ is a staining kit for performing the so-called Prussian blue (Berlin blue) reaction in hematological and histological specimen material. This staining kit contains all the reagents necessary for the detection of free ionic iron. In the Prussian blue reaction, ionic iron (Fe3+) not bound to the heme structure reacts with potassium hexacyanoferrate(II) in hydrochloric solution. It precipitates as an insoluble complex salt in the blood, bone-marrow, or tissue cells and thus localizes free cellular iron: 4 Fe3+ + 3 K4Fe(CN)6 = Fe4[Fe(CN)6]3 + 12 K+
As a measure to achieve the best possible visual differentiation of the iron deposits in the cytoplasma, this is counterstained with nuclear fast red solution (Nuclear fast red-aluminum sulfate solution 0.1% (Cat. no.100121), resulting in a tender pink color. If further, more detailed information on the cell morphology is required, counterstaining with any of the other familiar “classical” methods such as Giemsa, (Giemsa, Cat. no. 109204), May-Grünwald (May-Grünwald eosin methylene blue solution, Cat.no 101424), hemalum (Mayer’s hemalum solution, Cat. no.109249), etc. can also be employed.
The Prussian blue reaction can also be used to stain specimens already stained by one of these classical procedures for the additional detection of iron. Repeat counterstaining is not necessary in this case.
The staining kit is sufficient for 6 – 8 stainings with up to 16 slides. The staining kit is developed and registered as CE / IVD product for applications in diagnostics. For more details, please see instructions for use (IFU). The IFU can be downloaded from this webpage.
