neb cleavage supercoiled dna

This enzyme has shown to have lower activity on some supercoiled plasmids with more than 1 unit required to digest 1 μg plasmid dna. For complete digestion of 1 μg of plasmid dna please follow our recommended digestion protocol. Enzymes are incubated overnight with lambda dna to confirm that there is no additional non specific nuclease activity present.

This enzyme has shown to have lower activity on some supercoiled plasmids with more than 1 unit required to digest 1 μg plasmid dna. A 70 alcohol wash or dialysis can be used to remove the salt. Mini prep dna containing residual salt is resistant to cleavage.

Sphi we are excited to announce that we are in the process of switching all reaction buffers to be bsa free.

Neb cleavage supercoiled dna. Beginning april 2021 we will be gradually transitioning to buffers containing recombinant albumin ralbumin for restriction enzymes and some dna modifying enzymes. All information on the website has been updated to reflect this change. Cleavage of mammalian genomic dna is blocked by cpgmethylation. Saci is inhibited by salt concentrations 10 mm.

Cloning qc ligation and re cutting a dna template is over digested by the appropriate restriction enzyme and the percentage of dna fragments ligated and re cut are determined by agarose gel electrophoresis.
