Maximize the yield of target nucleic acids. Proteinase K is rigorously tested for the absence of nucleases.
Experience stability and flexibility. The lyophilizate is very stable and can be stored at room temperature for at least 12 months. A broad range of fill volumes from 25 mg to 5 g per vial is available. Lyophilizate dissolved in water is stable for at least 60 days when stored at +2 to +4°C.

"Value": "Proteinase K, recombinant, PCR Grade, digests proteins very efficiently. It can be used to rapidly inactivate endogenous RNases and DNases during nucleic acid isolation or remove enzymes that have been used during (m)RNA synthesis by in vitro transcription, as in the manufacture of mRNA vaccines. Proteinase K is also used to:
Isolate native RNA and DNA from tissues and cell lines by promoting cell lysis
Analyze membrane structures by modifying proteins and glycoproteins on cell surfaces
Remove cellular debris during the preparation of colony lifts
Treat tissue sections to ensure efficient probe infiltration during in situ hybridization

"Value": "Proteinase K, originally isolated from the mold Tritirachium album, is a recombinant enzyme expressed in Pichia pastoris. It is a highly active, subtilisin-related serine endopeptidases that does not exhibit any pronounced cleavage specificity. Thus, Proteinase K, recombinant, PCR Grade, is a universal tool for template preparation. Amino acid sequence and molecular structure of the recombinant enzyme and the native protease are identical. However, the production process of the recombinant Proteinase K guarantees an enzyme of outstanding reliability and purity meeting all requirements of diagnostics' manufacturers. Special emphasis has been placed on a low DNA-content of the enzyme preparation, making Proteinase K, recombinant, PCR Grade, ideally suited for isolating PCR and RT-PCR templates.",

"Value": "Nomenclature: Proteinase K Molecular weight: 28.8 kD pH optimum: 7.5-10.5 Inhibitors: Proteinase K is inhibited by diisopropyl fluorophosphate and phenylmethylsulfonyl fluoride (PMSF) and is also totally inactivated by mercuric ions. Pefabloc® SC and Pefabloc® PLUS are specific, irreversible and nontoxic inhibitors. Specificity: Proteinase K is one of the most active endopeptidases known and does not exhibit any pronounced cleavage specificity. Activity can be stimulated by addition of denaturing agents (SDS and urea).",
