Tryptone USP
Tryptone USP is suitable for a wide variety of uses in general bacteriology for the preparation of culture media. As a result of its high tryptophan concentration, it is used for the detection of indole production. Lacking fermentable carbohydrates, it is included in media used to study sugar fermentations.
Because of its compatibility with other ingredients, peptones or extracts, Tryptone USP is included in the composition of media intended for the growth and enumeration of bacteria in water, milk, other food products, pharmaceuticals and cosmetics. Combined with papaic digest of soybean meal, it is used for the preparation of Tryptone Soy Broth and Tryptone Soy Agar.

In compliance with regulatory requirements, a USDA permit (VS 16-3) is mandatory for shipments from Canada to the USA due to the inclusion of peptone, an animal byproduct.
Tryptone USP is obtained by the pancreatic digestion of a high quality casein. As a result of the relatively constant purity of the starting material used, Tryptone USP furnishes efficient and consistent results, in particular in studies on the metabolism and growth of various microorganisms.
The method of preparation has been designed to maximize the reduction in calcium levels in the finished product. Tryptone USP can be used to prepare phosphate-containing media characterized by their clear, light nature, as well as by the absence of significant precipitates after autoclaving.
