DNaseMe, dsDNaza (EN33)

DNaseMe is a 42.8 kDa recombinant endonuclease, derived from marine amphipods, expressed in Pichia pastoris. The enzyme displays high specific activity towards double-stranded DNA leaving single-stranded DNA or RNA undamaged in standard conditions. DNaseMe is highly active in a broad spectrum of temperatures, buffer conditions and pH. The specific activity is similar to bovine DNase I however, DNaseMe is characterized by higher stability in demanding reaction and storage conditions (e.g. high salt and detergent containing buffers, elevated temperature). These features make DNaseMe extremely useful for rapid and “RNA safe” degradation of genomic DNA, where absence of ribonucleases is critical to maintain the integrity of RNA.

Masterase, HL-dsDNaza (EN31)

Masterase is a 43.3 kDa heat-labile recombinant endonuclease, derived from a cold water eukaryotic organism, expressed in Pichia pastoris. The enzyme displays high specific activity towards double-stranded DNA leaving single-stranded DNA or RNA undamaged in standard conditions. Masterase can be easily inactivated by heat treatment in moderate temperatures. It is intended for applications where the presence of dsDNA influences experiments’ results in thermo-sensitive applications and it is extremely useful for rapid and safe purification of RNA or proteins samples from contaminating DNA.

Saltonase, HL-Nukleaza (EN32)

Saltonase is a 28.4 kDa, cold-active, heat-labile recombinant endonuclease produced in E.coli. Saltonase originates from psychrophilic bacteria and effectively digests all types of DNA and RNA substrates in different buffer conditions and a broad range of temperatures. It is very active in demanding conditions, including low temperatures and environment with high salt content. These features make Saltonase extremely useful for removing undesired nucleic acids contamination during purification of proteins in laboratory and manufacturing workflows.

RNaza A (RP145)

Rybonukleaza A (RNaza) jest endorybonukleazą degradującą z wysoką aktywnością ssRNA, dsRNA oraz RNA w hybrydowych cząsteczkach RNA-DNA w środowisku o niskiej zawartości soli (do 100 mM NaCl), natomiast w środowisku o stężeniu soli powyżej 300 mM RNaza A trawi głównie cząsteczki jednoniciowego RNA.

RNaza H (RT34)

RNaza H to rekombinowana endorybonukleaza 18,9 kDa oczyszczona ze szczepu Escherichia coli. Enzym specyficznie hydrolizuje wiązania fosfodiestrowe pomiędzy RNA i cDNA, wytwarzając 5’ terminalne oligorybonukleotydy zakończone fosforanem i jednoniciowe DNA. RNaza H nie degraduje jedno- i dwuniciowego DNA ani niezhybrydyzowanego RNA.
