Thermo Fisher, 211677, Bacto™ Peptone

Bacto™ Peptone is used as a nutrient-rich nitrogen source in microbial and selected mammalian or insect cell-culture media. The powder is an animal-origin enzymatic digest of bovine and porcine proteins and provides a complex mixture of peptides, amino acids and other growth-supporting constituents. It is commonly incorporated into media for cultivation of heterotrophic microorganisms and can support organisms such as Escherichia coli, Saccharomyces cerevisiae and other production strains. Applications include microbial fermentation, biotherapeutic production, animal-health vaccine processes and media formulation. This configuration contains 500 g in a bottle. The powder has a shelf life of approximately five years under the stated conditions and should be kept in a cool, dry environment at 2–25°C in a well-sealed container.
