Description
Tryptone/Peptone ex casein, granulated is a pancreatic digest of casein supplied as a granulated reagent for microbiology. Identified by CAS number 91079-40-2 and EG nr. 293-428-4, it serves as a nitrogen-rich peptone component in culture media and related life-science preparations. The product is Manufactured by Carl ROTH, this tryptone/peptone supports microbiological work including media formulation for cultivation and broader laboratory applications linked to genetic engineering and virus-related research contexts listed for the material. The granulated texture facilitates accurate dosing and dissolution when building broths or agars. As a pancreatically digested casein peptone, it provides peptides and amino acids commonly required in microbial growth media. Laboratories can use it as a defined peptone source within established recipes without changing handling routines typical for dehydrated media ingredients. Consistent granulation supports reproducible weighing across successive media batches in research and quality-control environments.

Questions about Tryptone/Peptone ex casein, granulated, 250 g, pancreatically digested
What is this article?
Tryptone/Peptone ex casein, granulated, 250 g, pancreatically digested 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.
