  • FAQ: How does the level of star activity of SspI-HF compare to SspI?

    The Fidelity Index which measures the minimum units to produce star activity was determined using the following conditions; 1X NEBuffer, 5% glycerol, lambda DNA (1µg/50 µl), incubated for 1 hour at 37˚C . The minimum number of units of SspI-HF required to produce star activity in the recommended NEBuffer 4 is (500 units). The minimum number of units of SspI required to produce star activity in NEBuffer 4 is (16 units).
