Description
Peptone ex casein, tryptic digest is a microbiological nutrient component obtained by tryptic digestion of casein. Registered under CAS number 91079-40-2 and EG number 293-428-4, it is intended for microbiology and supports formulation of culture media where a reliable source of peptides and amino acids is needed. The material is widely used in growth media for bacteria and other microorganisms in research, quality-control and teaching laboratories. This peptone from manufacturer Carl ROTH is positioned for microbiological applications and integrates into standard media recipes requiring casein-derived peptone. Its defined origin as a tryptic digest helps laboratories maintain consistent nutrient profiles across batches of broths and agars used in microbial cultivation and related biochemical studies.

Questions about Peptone ex casein, tryptic digest, for microbiology, 500 g, plastic
What is this article?
Peptone ex casein, tryptic digest, for microbiology, 500 g, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Biochemicals (other), inside Biochemicals & reagents, in Microbiology lab supplies.
These are the biochemical reagents that are not an amino acid, a sugar, a lipid, an enzyme or an antibiotic. Identity and purity still decide the bottle. If the compound is light-sensitive or hygroscopic, the handling on the label is part of the specification.
A biochemical is a molecule of life, sold as a reagent: an amino acid, a sugar, a nucleotide, a lipid, an enzyme, an antibiotic. The difference from a bulk chemical is that the use is a biological one, and the impurities that matter are the ones that change that use. An enzyme is specified by activity, not only by mass. An antibiotic is specified by potency. Papers are on PubMed. Structures are on PubChem. Strains and lines that consume these reagents are at ATCC.
