Casein Digest Peptone

Casein Digest Peptone is an enzymatic digest of casein for use in preparing microbiological culture media in a laboratory setting. Casein Digest Peptone is not intended for use in the diagnosis of disease or other conditions in humans.

Casein is the main protein of milk, and a rich source of amino nitrogen. Casein Digest Peptone was developed for use in molecular genetic media formulations, including NZCYM Broth, NZYM Broth, and NZM Broth. The enriched formulations of NZ media are used to cultivate recombinant strains of E. coli and propagating theta bacteriophages.
