Description
Proteinase K, lyophilised, is a BioScience-Grade enzyme preparation offering a minimum activity of 35 U/mg for molecular biology and nucleic acid isolation work. It is identified by CAS number 39450-01-6 and EG number 254-457-8 In DNA and RNA isolation protocols, Proteinase K is employed to digest proteins during purification and sample preparation steps that support recovery of nucleic acids. The lyophilised form facilitates handling prior to reconstitution according to laboratory procedures, while the BioScience-Grade quality level and minimum activity of 35 U/mg provide clear specification points for method documentation. size suits both method development and routine isolation batches in research and analytical settings. This reagent comes from manufacturer Carl ROTH within its life-science portfolio aimed at purification workflows. Laboratories engaged in molecular biology can integrate the material wherever a defined proteinase activity is required for DNA/RNA isolation. The product is intended for professional use in environments that specify lyophilised Proteinase K at this activity grade.

Questions about Proteinase K, lyophil., min. 35 U/mg, BioScience-Grade, 100 mg, glass
What is this article?
Proteinase K, lyophil., min. 35 U/mg, BioScience-Grade, 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.
