BioGnost’s Warthin Starry kit enables staining histology sections and Helicobacter pylori visualisation in a simple way and in a few steps. The kit is distinctive because it contains 12 containers with gelatine used for practical incubation and section staining. By adding other reagents, it is possible to create an active developing solution used for immersing sections and simultaneous staining of 1 to 4 sections. Staining using the Warthin Starry kit is based on reducing silver nitrate to silver using hydroquinone. The formed silver is deposited on the surface of Helicobacter pylori. The microscopic image shows the bacteria-stained dark brown to black, the cells are stained yellow-brown, and the nuclei brown. The bacteria may be detected in the mucus of surface epithelium, in apical glands of the stomach, and in the mucosa of the stomach.
Warthin Starry kit
Five-reagent kit for staining Spirochaeta, Helicobacter pylori, Microsporidia and Legionella pneumophila. The kit contains 12 jars with gelatine that enables both incubation and staining of sections, as well as other reagents that enable precipitation of silver on the bacterial surface. The bacteria are found in the mucus of the surface epithelium, in the apical gastric glands and in the gastric mucosa.
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.
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.
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.
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.
Martius Scarlet Blue (MSB) kit, 6x100ml+1x250ml
Seven-reagent kit used for fibrin visualisation, especially of older clusters. This method is a modification of Masson Trichrome and is ideal for studying connective tissue and vascular pathology.
