FAQ
- This depends on the application. DSN is a highly versatile enzyme, and the input amount can be adjusted to meet specific requirements. The amount of DSN and incubation times will vary based on the desired product. For example, a typical amount of DSN used for the normalization of cDNA libraries ranges from 0.25 to 1 U.
- To protect ssDNA in a pool of dsDNA/ssDNA, we recommend titrating the enzyme amount to determine the optimal conditions for ssDNA protection.
The incubation temperature can be adjusted between 25°C and 70°C, with an optimal temperature of 60°C.
DSN is susceptible to EDTA inactivation at concentrations of 5 mM and above. We recommend performing an inactivation step by adding 5 mM EDTA at the reaction temperature for 5 minutes following digestion.
DSN is thermally stable and retains activity when heated to 98°C for 10 minutes. We suggest stopping all reactions with DSN by incubating with 5 mM EDTA for 5 minutes at 60°C.
