Reaction Temperature: 25°C

Prototype: SmaI

Inactivation Temperature (20 min): 65°C

Reaction Buffer:

1x Acet Buffer: 20 mM Tris-acetate (pH 7.5 at 37°C), 10 mM magnesium acetate, 50 mM potassium acetate, 1 mM dithiothreitol, 100 µg/ml bovine serum albumin.

Unit Definition: One unit is the amount of enzyme required to completely digest 1 µg of Ad-2 DNA in 1 hr in a total reaction volume of 50 µl.

Assay Conditions: 20 mM Tris-acetate (pH 7.5 at 37°C), 10 mM magnesium acetate, 50 mM potassium acetate, 1 mM dithiothreitol, 100 µg/ml bovine serum albumin and 1 µg of Ad-2 DNA. Incubation is at 25°C for 1 hr in a reaction volume of 50 µl.

Storage Buffer: 10 mM Tris-HCl (pH 7.5 at 22°C), 150 mM KCl, 0.1 mM EDTA, 1 mM dithiothreitol, 100 µg/ml bovine serum albumin and 50% (v/v) glycerol.

Storage Conditions: Store at –20°C.

Quality Control:

Non-specific Endonuclease: Incubation of 10 units of SmaI with 1 µg of Ad-2 DNA at 25°C for 16 hrs (a 160-fold over-digestion) resulted in the same sharp characteristic banding pattern as the standard assay reaction, as determined by agarose gel electrophoresis.

3'-Exonuclease: 5, 10 and 20 units of SmaI and 0.13 µg of 3'-ends of lambda/TaqI fragments (3'-labeled with T4 DNA Polymerase and [³H]dGTP and [³H]dCTP), incubated for 1 hr at 25°C resulted in 0.0 slope of %-end label released per unit of enzyme. Reaction volume 10 µl.

5'-Exonuclease/5'-Phosphatase: Incubation of 5, 10 and 20 units of SmaI with 0.05 µg of 5'-ends of [5'-³²P] lambda/HaeIII fragments for 1 hr at 25°C resulted in 0.01 slope of %-end label released per unit of enzyme. Reaction volume 10 µl.
