Bacto Proteose Peptone No. 2 is member of the Bacto Proteose Peptones, which are enzymatic digests of protein.

• 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

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.

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