Cryonase Cold-Active Nuclease
Cryonase Cold-Active Nuclease is a recombinant endonuclease originally derived from a psychrophile, Shewanella sp., and purified from E. coli. This endonuclease enzyme can complete digestion of all types of DNA and RNA (single-stranded, double-stranded, linear or circularized) at cold temperatures and even in samples placed on ice. As a result, Cryonase Cold-Active Nuclease is frequently used during DNA digestion of mixed samples, such as those that include heat-labile proteins.
- Digestion of all types of DNA
- Digestion of all types of RNA
- Enzymatic and other heat-labile reactions
- Protease activity is less than the detection limit
- E. coli genomic DNA contamination is less than the detection limit
Supplied in a buffer (20 mM NaCl, 10 mM Tris-HCl (pH 7.5), 50% glycerol, 2mM MgCl2)
