Gomori Trichrome kit is used for the analysis of collagen fibres in the liver and kidneys, in order to achieve easier differentiation of collagen and smooth muscle fibres, as well as for distinguishing destroyed fibres (present in cases of mitochondrial myopathies).
Gomori Trichrome kit
Five-reagent kit for staining muscle, collagen fibre and nuclei, contains blue counterstain. The kit can be used to contrast skeletal, cardiac or smooth muscle.
Alcian Yellow Toluidine Blue kit
Six-reagent kit for staining Helicobacter pylori in gastric tissue sections. This method is one of the most popular non-silver methods for staining of H. pylori, where bacteria are stained blue in contrast to yellow mucins.
Mallory Trichrome kit
Three-reagent staining kit for connective tissue visualisation and detection of collagen, cartilage, muscle, elastic fibres, mucous, pituarity cells, reticulum, bones, amyloid and erythrocytes.
Giemsa HP kit
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.
BioGram 4 kit
Four-reagent kit for identification of bacteria according to Gram. Kit contains Gram Crystal Violet 1% solution, stabilized Gram Lugol solution, double amount of Gram Decolorizer solution 2 and Gram Safranin solution as counterstain.

P.A.S. Diastase Kit
BioGnost’s P.A.S. Diastase kit is most commonly used for identifying glycogen in liver. Periodic acid enables the molecules containing glycol groups to create aldehydes affected by Schiff’s reagent staining them violet (magenta). Specific stains are created by applying the PAS method on unsubsti-tuted polysaccharides, mucoproteins and glycoproteins, glycolipids and phospholipids. Alpha-amylase enzyme (also known as diastasis) is used for differentiation between glycogen and other PAS-positive structures by dissolving 1→4 glycosidic bonds, causing the glycogen to remain unstained after the PAS reaction. BioGnost’s P.A.S. Diastase kit uses thermostable enzyme which does not require heating to +37°C to be active, but incubat-ing the section at +37°C is preferred in order to achieve better glycogen breakdown. The same tissue section is used as negative control for this reaction, but the sample is not treated using alpha-amylase.

HE Rapid Staining kit- frozen and paraffin sections
Ready-to-use eight-reagent kit (in 16 containers that can be used as staining jars) for rapid HE staining of frozen and paraffin tissue sections in histopathology. Contains xylene substitute as clearing agent and xylene substitute-based medium for permanent section covering.
