Assayed onAdenovirus -2 DNA
Unit definitionOne unit of the enzyme is the amount required to hydrolyze 1 μg of Adenovirus -2 DNA in 1 hour at 37°C in a total reaction volume of 50 μl.
Optimal SE-bufferY (33 mM Tris-acetate (pH 7.9 at 25°C); 10 mM magnesium acetate; 66 mM potassium acetate; 1 mM DTT.)
Enzyme activity (%)
75 - 10050 - 750 - 100 - 1010050
Optimal temperature
Storage conditions20 mM Tris-HCl (pH 7.6); 50 mM NaCl; 0.1 mM EDTA; 1 mM DTT; 200 μg/ml BSA; 50% glycerol. Store at -20°C.
LigationAfter 3-fold overdigestion with enzyme 95% of the DNA fragments can be ligated. Of these 90% can be recut.
