  • BP4200: Recombinant Dr. Nuclease (Benzonase Nuclease Alternative)

    Source: E. coli-derived.
    Specific activity: ≥1.75 x 10^6 U/mg. One unit of Dr. Nuclease corresponds approximately to the required amount of enzyme to digest 37 μg of DNA in the reaction buffer, 50 mM Tris-HCl, pH 8.0, 1 mM MgCl2, for 30 minutes at 37°C.
    Purity >98% by SDS-PAGE.

     

    BP4200-GMP: Recombinant Dr. Nuclease (Benzonase Nuclease Alternative), GMP Grade

     

    Source: E. coli-derived.
    Predicted molecular mass: ~28 kDa.
    Specific activity: ≥1.75 x 10^6 U/mg. One unit of Dr. Nuclease is defined as the amount of enzyme required to produce a change in absorbance at 260nm of 1.0 in the time of 30 minutes, under optimum conditions with excess substrate.
    Purity: ≥95% by SDS-PAGE and ≥99% by SEC-HPLC. It does not contain any antimicrobial preservatives or protein stabilizers except glycerol (of synthetic origin).
    Formulation: 0.2 μM filtered solution (250 units/ul) of 20 mM Tris-HCl, pH 8.0, 2 mM MgCl2, 2 mM NaCl, 50% Glycerol.
