Description
La protéinase K lyophilisée est une sérine protéase à large spectre fournie avec une activité minimale de 30 U/mg pour les flux de travail en biologie moléculaire. Identifiée par le numéro CAS 39450-01-6 et le numéro EG 254-457-8, cette enzyme est largement utilisée dans les protocoles d'isolement d'ADN et d'ARN où une digestion efficace des protéines et une inactivation des nucléases sont requises. La présentation lyophilisée permet un stockage pratique et une reconstitution immédiatement avant l'utilisation. Proposée par le fabricant Carl ROTH, la protéinase K s'intègre facilement dans les kits d'isolement établis et les systèmes de tampons personnalisés. Son activité protéolytique robuste dans des conditions dénaturantes en fait un choix standard pour clarifier les lysats riches en protéines avant les analyses d'amplification, de séquençage ou d'hybridation en aval.

Questions about Protéinase K, lyoph., min 30 U/mg, 25 mg, verre
What is this article?
Protéinase K, lyoph., min 30 U/mg, 25 mg, verre is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Enzymes & substrates, inside Biochemicals & reagents, in Milieux microbiologiques.
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 Milieux microbiologiques.
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.
