General description: Tryptose is a mixed enzymatically digested protein with unique nutritional properties. The digest conditions are such that it contains many different peptides including those of higher molecular weight (proteoses). It is used to grow the most fastidious of organisms especially when a rapid growth is required. Tryptose is also recommended to demonstrate haemolytic reactions on a blood agar base.
