Web10X DNase I Buffer 5 μl Recombinant DNase I (RNase-free) 2 μl (10 U) Ribonuclease Inhibitor 20 U DEPC-treated water up to 50 μl 2. Incubate for 20 - 30 min at 37℃. 3. Perform one of the following procedures to inactivate DNase I. A．Heat treatment (1) Add 2.5 μl of 0.5 M EDTA, and incubate at 80℃ for 2 min. WebHeat inactivation: Probably the most common method of DNase inactivation is heat treatment, typically for 5 minutes at 75°C. Although this method appears straightforward, the divalent cations in the DNase digestion buffer can cause (chemically-induced) strand scission of RNA when heated.
