The Warthin-Starry silver stain is used to specifically detect the bacterium Helicobacter pylori in histological specimens. The bacteria are found in the mucus of the surface epithelium, in the apical gastric glands and in the veolae of the gastric mucosa. They appear dark brown to black in the microscopic image, whereas surrounding cells are stained yellow and the nuclei brown. The Kit contains four reagents: 6% Silver nitrate solution, Hydroquinone mixture, Gelatine powder and 1.2% Acetic acid solution, which are ready-to-use. To prevent fading, the staining preparations need to be cover-slipped with DPX or Neo-Mount®; an alternative xylene-containing covering agent can be used if an additional silver-fixing step with sodium thiosulfate is included previous covering.
