  • RQ1 RNase-Free DNase is a preparation of deoxyribonuclease (DNase) I that degrades single-stranded or double-stranded DNA to produce 3´-hydroxyl oligonucleotides. The enzyme is provided with 10X Reaction Buffer (400mM Tris-HCl [pH 8.0 at 25°C], 100mM MgSO4, 10mM CaCl2) and Stop Buffer (20mM EGTA [pH 8.0 at 25°C])


    • Preparation of DNA-free RNA.
    • Degradation of DNA from RNA transcription systems.
    • Nick translation of DNA.
    • Studying DNA:protein interactions by DNase I footprinting.

    Storage Buffer: 10mM HEPES (pH 7.5 at 25°C), 50% (v/v) glycerol, 10mM CaCl2, 10mM MgCl2.

    Source: Bovine pancreas.

    QC Tests: Activity, RNase.

    Unit Definition: One unit is defined as the amount of enzyme required to completely degrade 1ug of DNA in 10 minutes at 37°C in 50ul of a buffer containing 40mM Tris-HCl (pH 7.9 at 25°C), 10mM NaCl, 6mM MgCl2, 10mM CaCl2.
