Fouchet-Van Gieson kit

Three-reagent kit for visualisation of bilirubin and collagen according to Kutllick. Bilirubin is a yellow-brown pigment, but changes to green due to oxidation induced by Fouchet reaction. Green bilirubin can easily be detected on yellowish and pink coloured background.

Grimelius kit

Five-reagent kit for staining argyrophilic granules. Grimelius kit can be used for the detection of secretory intracytoplasmatic granules specific for carcinoid tumours and for identification of neuroendocrine cells.

HemoGnost Perls kit

Three-reagent HemoGnost Perls (Prussian blue / Berlin blue) kit for the detection of reactive ferric (Fe3+) (not bound to haemoglobin) ions in cells. It is often applied on bone marrow and spleen cells.

Masson Fontana kit

Six-reagent melanin and argentaffin granule staining kit, based on the reduction of silver nitrate to elemental silver. Melanin is a brown-black pigment normally present in the hair, skin, retina, iris and certain parts of CNS. Argentaffin granules are found in carcinoid tumours.

Orcein kit

Five-reagent kit for visualisation of hepatitis B surface antigen (HBsAg) seen as viral inclusion bodies in hepatocytes, for elastic fibres and copper associated protein in tissue sections. It can be used with frozen sections.

Rhodanine kit

Four-reagent kit for detecting copper and copper-associated protein (CAP) in patients suffering from Wilson’s disease. Abnormal copper accumulations are predominately found in liver tissue, but can also be found in the brain and cornea of the eyes.

Von Kossa kit

Five-reagent kit for simple and reproducible detection of calcium deposits and calcium salt in tissue samples according to Von Kossa. Tissue calcification is associated with metabolic problems in various tissues (like bone marrow and mamma) and in tumours.
