Recognition Sequence :
Unit Definition :
One unit of the enzyme is the amount required to hydrolyze 1 μg of Lambda DNA in 1 hour at 37°C in a total reaction volume of 50 μl.
Reaction Temperature :
Storage Buffer :
10 mM Tris-HCl (pH 7.5); 100 mM NaCl; 0.1 mM EDTA; 7 mM 2-mercaptoethanol; 100 μg/ml BSA; 50% glycerol
After 3-fold overdigestion with enzyme more than 90% of the DNA fragments can be ligated and recut.
Acinetobacter calcoaceticus 36
Working buffer :
Y (33 mM Tris-acetate (pH 7.9 at 25°C); 10 mM magnesium acetate; 66 mM potassium acetate; 1 mM DTT.)
Non-specific hydrolisis :
No nonspecific activity was detected after incubation of 1 μg of Lambda DNA with 4 u.a. of enzyme for 16 hours at 37°C.
Concentration, u.a./ml :
20min Under 65°C
Reagents Supplied :
10 X SE-buffer Y
High enzyme concentration may result in star activity.
