New! Von Kossa Method for Calcium Kit ......................................
Demonstrates only calcium phosphate and calcium carbonate salts. Note that
when used in skin specimens that the silver will reduce the melanin in the skin,
to also give a black deposit. Used as a bone stain to indicate osteomalacia, or in
other paraffin embedded tissues to stain calcium deposits seen in metabolic diseases,
Paget’s disease, renal osteodystrophy and hyperpara- thyroidism, necrotic
areas associated with TB, infarction (Gandy Gamna bodies), atheroma in blood
vessels and Malakoplakia in the bladder (Michaelis-Gutman bodies).
Technical Data Sheet #726
Kit Contains: 3% Silver Nitrate, 5% Sodium Thiosulfate, Nuclear Fast Red
New! Warthin-Starry Stain Kit ...............................................
Identifies Spirochetes and other bacteria such as H. pylori and two causative
agents of cat scratch disease, Bartonella henselae and Afipia felis. Warthin-
Starry Stain relies on the ability of certain bacteria to bind silver ions from solution.
Subsequent addition of a reducing agent then converts this bound silver
to visible metallic silver. In the Warthin-Starry stain, tissue is sensitized prior to
application of the silver complex. An aqueous silver nitrate solution combined
with the reducing agent hydroquinone is applied and a silver diamine complex
is generated. Technical Data Sheet #910
Kit Contains: 1% Silver Nitrate, 2% Silver Nitrate, 5% Gelatin Soln., 0.15% Hydroquinone Soln.
