Description: New England Biolabs supplies a 10X reaction buffer with all of its enzymes. At a 1X concentration this reaction buffer assures optimal activity of the enzyme.
Reagents Supplied: 10X DNase I Reaction Buffer
1X DNase I Reaction Buffer:
10 mM Tris-HCl
2.5 mM MgCl2
0.5 mM CaCl2 pH 7.6 @ 25°C
RNase Activity: Incubation of DNase I at 1X concentration with 100 units of DNase I and 10 μg of double-stranded RNA Ladder for 2 hours at 37°C resulted in the same electrophoretic profile as untreated RNA.
Incubation of DNase I at 1X concentration with 2 units of DNase I and 10 μg of single-stranded RNA Ladder for 1 hour at 37°C resulted in the same electrophoretic profile as untreated RNA.
