Yeast Extract (Gibco™)

Yeast Extracts are concentrates of the water-soluble portion of autolyzed Saccharomyces cerevisiae cells. They are derived from primary grown baker’s yeast. These animal origin-free products are suitable for use as multi-functional nutritional supplements in mammalian cell culture, microbial fermentation, and insect cell culture applications. Yeast extract provides essential water-soluble vitamins, amino acids, peptides, and carbohydrates to any medium formulation.

Bacto™ Proteose Peptone (Gibco™)

Bacto Proteose Peptones are enzymatic digests of protein. Studies of peptic digests of animal tissue prepared under varying digestion parameters demonstrated that no single peptone is the most suitable nitrogen source for every microbiological application. These findings led to the development of Bacto Proteose Peptone, Bacto Proteose Peptone No. 2, and Bacto Proteose Peptone No. 3. Bacto Proteose Peptone No. 4 is a spray-dried version of Bacto Proteose Peptone.

• Bacto Proteose Peptone is used in preparing microbiological culture media and in producing bacterial toxins
• Bacto Proteose Peptone No. 2 is used in preparing microbiological culture media
• Bacto Proteose Peptone No. 3 is used in preparing microbiological and mammalian cell culture media
• Bacto Proteose Peptone No. 4 is a spray-dried version of Bacto Proteose Peptone. It offers the same beneficial nutrients as Bacto Proteose Peptone for growth promotion and toxin production in a wide range of fastidious microorganisms.

We also offer alternatives to Bacto Proteose Peptones for scale-up to production applications, including BiTek Proteose Peptone.
