In short Tris maintains the constant pH and EDTA chelates the metal ion and inactivates DNase and RNase. Dilute a preparation of RNase-free DNase I to a concentration of 10 unitsμl using DNase dilution buffer. 40 mM Tris-HCl pH 75.

Incubate at 37C for 10 minutes. Inactivation of TURBO DNase Inactivate TURBO DNase using one of the following methods. Aliquot and freeze at -20 C.

At this point you can either use the DNase-inhibitor resin included in the kit which takes all of 5 minutes to remove the DNase or you can repeat the phenol-chloroform extraction which takes another day and a half. To digest DNA during bacterial lysis add to a final concentration of 10 gmL in lysis buffer with 5 mM MgCl 2. 100 mM Tris-HCl pH 75 25 mM MgCl2 1 mM CaCl2.

Commercial versions use SDS but at higher concentrations 1 the SDS will tend to crash out.

You can make it in DEPC treated water to get rid of RNase. The recipe of DNase buffer is. To treat with DNaseI Turbo-DNase Ambion add 4μl of DNase buffer and 1μl of DNaseI.

Heat to 100 C for 15 minutes allow to cool to room temperature then adjust to pH 74 using 01 volume of 1. At a 1X concentration this reaction buffer assures optimal activity of the enzyme. New England Biolabs supplies a 10X reaction buffer with all of its enzymes.

Incubate at 37C for 20 to 30 minutes. Use a clean spatula for each ingredient or carefully pour each ingredient from its bottle. 25122018 Here is the lysis buffer recipe for plant DNA extraction.
