Description: New England Biolabs supplies a 10X reaction buffer with all of its enzymes. At a 1X concentration this reaction buffer assures optimal activity of the enzyme.
1X Antarctic Phosphatase Reaction Buffer:
50 mM Bis-Tris-Propane-HCl
1 mM MgCl2
0.1 mM ZnCl2 pH 6.0 @ 25°C
Quality Control for Current Lot
Non-specific DNase Activity (16 Hour): A 50 µl reaction in 1X Antarctic Phosphatase Reaction Buffer containing 1 ug of HaeIII digested ΦX174 RF I DNA incubated for 16 hours at 37°C results in a DNA pattern free of detectable nuclease degradation as determined by agarose gel electrophoresis.
Endonuclease Activity (Nicking): A 50 μl reaction in 1X Antarctic Phosphatase Reaction Buffer containing 1 μg of supercoiled ΦX174 RF DNA incubated for 4 hours at 37°C results in <10% conversion to the nicked form as determined by agarose gel electrophoresis.
