Description
E. coli O157:H7 chromogenic agar (base) is a dehydrated nutrient medium for microbiology, presented as a 500 g quantity in plastic packaging. This chromogenic agar base supports laboratory preparation of solid culture media used in work with coliforms and Escherichia coli, with particular relevance to E. coli O157:H7. The dehydrated form is reconstituted in the media kitchen, then dispensed as plates or other solid formats according to the laboratory method. A 500 g pack suits facilities that prepare chromogenic media in batches. Plastic packaging keeps the dehydrated medium contained during handling and weighing. From manufacturer Carl ROTH, the article belongs to dehydrated nutrient media for microbiology and is grouped with media for coliforms and E. coli. Chromogenic bases are chosen when colony appearance on agar is part of the reading workflow after incubation. The product name identifies both the target organism group and the chromogenic principle of the finished medium. The base designation shows that the complete medium is prepared from this dehydrated starting material.
This article is part of Enzymes & substrates, in Biochemicals & reagents.

Questions about E. coli O157:H7 chromogenic agar (base)
What is this article?
E. coli O157:H7 chromogenic agar (base) is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Enzymes & substrates, inside Biochemicals & reagents, in Microbiology lab supplies.
An enzyme is sold by activity, in units defined by a stated reaction, not only by milligrams. Source and specific activity are the specification. A substrate is the molecule that enzyme converts, often a chromogenic one so the reaction can be seen. Units from two suppliers are comparable only when the definition matches.
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.
Which category should I open next?
