PR1MA™ Cod Uracil-DNA Glycosylase

PR1MA™ Cod Uracil-DNA Glycosylase (cUNG) is a recombinant, thermolabile enzyme that removes uracil from DNA.

PR1MA™ β - Agarase

PR1MA™ β - Agarase has a high tolerance to inhibitors in electrophoretic buffers such as TBE and TAE, eliminating the need to perform a buffer exchange step before digestion. PR1MA™ β - Agarase has higher thermal stability than other commercially available β - agarases, with a broad range of activity between 42°C and 50°C. Higher temperature digestion reduces the chances of residual agarose gelling at the end of the reaction, resulting in higher recovery of DNA or RNA.

Benefits

• Complete digestion of agarose, with no agarose fragments, left after the digestion
• Obtain DNA or RNA faster - no buffer exchange needed, with direct digestion in TAE or TBE
• Concentration: 1000 u / mL
