  • BP000872-ENZ-069: Recombinant Mouse Dihydrofolate Reductase

    Source: E. coli-derived.
    Specific activity is > 0.2 units/mg, in which one unit will convert 1.0 umole of 7,8 ?ihydrofloate and beta-NADPH to 5,6,7,8-tetrahydrofloate and beta-NADP per min at pH 6.5 at 25C.
    Purity > 95%, by SDS-PAGE.

  • BP000872-ENZ-443: Recombinant Human Dihydrofolate Reductase

    Source: E. coli-derived.
    Specific activity is 1.5 - 2.5 units/ml and was obtained by measuring the oxidation of NADPH in absorbance at 340 nm during reaction. One unit will convert 1.0 umole of 7,8 dihydrofolate and beta-NADPH to 5,6,7,8-tetrahydrofolate and beta-NADP per minute at pH 6.5 at 25C.
    Purity > 95%, by SDS-PAGE.
