Description
Proteinase K for bio analysis is a lyophilised enzyme preparation with a minimum activity of 30 mAnson U/mg, offered for molecular-biology and nucleic-acid workflows under CAS number 39450-01-6 and EG nr. 254-457-8. provides a practical laboratory quantity for DNA and RNA isolation, purification steps, and related sample-preparation protocols where broad proteolytic activity is required. Supplied in dry lyophilised form, the material supports flexible reconstitution according to established laboratory procedures. Categories such as life science, molecular biology, and DNA/RNA isolation reflect typical use in purification and dialysis-related work. Activity specification and identity data from manufacturer Carl ROTH enable straightforward comparison with existing enzyme stocks and method SOPs. The compact glass presentation suits cold-chain storage and controlled dispensing in research and diagnostic-support laboratories. Clear CAS and EG references aid inventory coding, safety documentation, and cross-site ordering consistency for routine bioanalytical applications.

Questions about Proteinase K, bio analysis,, lyophil., min. 30 mAnson U/mg, 100 mg, glass
What is this article?
Proteinase K, bio analysis,, lyophil., min. 30 mAnson U/mg, 100 mg, glass 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?
The category is Biochemicals & reagents. The sub-category is Enzymes & substrates. The catalogue is Microbiology lab supplies.
Shelves beside this one are Amino acids & peptides, Carbohydrates & sugars, Coenzymes, nucleotides & vitamins, Biochemicals (other), Antibiotics & antimycotics, Lipids, steroids & fatty acids and Detergents & surfactants.
What should I check before I order?
The technical information on this page is the manufacturer's sheet. Read that, not a rewritten specification.
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
