1X phi29 DNA Polymerase Reaction Buffer:
50 mM Tris-HCl
10 mM MgCl2
10 mM (NH4)2SO4
4 mM Dithiothreitol pH 7.5 @ 25°C
Quality Control for Current Lot
16-Hour Incubation:
A 50 µl reaction containing this reaction buffer at a 1X concentration and 1 µg of HaeIII digested ΦX174 RF I DNA incubated for 16 hours resulted in no detectable non-specific nuclease degradation.
Endonuclease Activity:
Incubation of this reaction buffer at a 1X concentration with 1 µg ΦX174 RF I DNA for 4 hours at 37°C in 50 µl reactions resulted in less than 5% conversion to RF II.
