Tryptone is a specially formulated enzymatic digest of casein, similar to Peptone from gelatin. It is used to supply higher growth rates when used in molecular biology media preparations such as YPD Broth and Agar. Used as a nitrogen source in culture media for fastidious and non-fastidious organisms. Also used to differentially select bacteria based on carbohydrate intake since Tryptone is carbohydrate deficient.

Certificate of Origin:
The raw animal product used in the manufacturing of Tryptone is derived from casein, a milk product derived from bovine, originating in New Zealand where there have been no reported cases of bovine spongiform encephalopathy (BSE). Tryptone is processed in Mexico. During processing of the product, a batch is heated to a minimum of 80°C for 1 hour including a minimum of 5 minutes at 105°C or greater and then dried at a minimum of 140°C. The enzyme used in processing is porcine-derived from the USA.
