Four-reagent kit for staining Helicobacter pylori in gastroscopic sections according to Lennart. Advantages of this method for detecting H. pylori are sensitive and reproducible results and easy performance.

Five-reagent kit for staining muscle, collagen fiber and nuclei, contains blue counterstain. The kit can be used to contrast skeletal, cardiac or smooth muscle.

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

Seven-reagent kit for visualization of fungi and histological argentaffin structures in general (such as basal membranes). Green counterstain provides clear and visually rich contrast to target structures stained black.

Three-reagent Hematoxylin-Basic Fuchsin-Picric acid staining kit for detection of cardiac muscle changes after ischemia or myocardial infarction. H.B.F.P. kit is a non-enzymatic histochemical technique for detection of early myocardial ischemia with vivid contrast.

Four-reagent Hematoxylin-Phosphotungstic Acid kit for differentiation of smooth and striated muscle tissues as well as for the detection of fibrin, collagen and elements of the central nervous system according to Mallory.

Acid-resistant hematoxylin according to Weigert. Two-reagent kit that stains the nuclei blue-black, often a component of special staining kits for connective tissues.

Three-reagent HemoGnost Perls (Prussian blue / Berlin blue) kit for the detection of reactive ferric (Fe3+) ions in cells. It is often applied on bone marrow and spleen cells.
