BioGnost’s Warthin Starry kit enables staining histology sections and Helicobacter pylori visualization in a simple way and in a few steps. The kit is distinctive because it contains 12 containers with gelatin 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.
