Description

Recognition site and hydrolysis position:

Source: Rhodopseudomonas sphaeroides
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.
Assayed on:
Lambda DNA
Optimal SE-buffer: SE-buffer B
Enzyme activity (%):

Storage conditions: 10 mM Tris-HCl (pH 7.5); 100 mM NaCl; 0,1 mM EDTA; 7 mM 2-mercaptoethanol; 100 μg/ml BSA, 50% glycerol. Store at -20°C.
Ligations:
After 20-fold overdigestion with enzyme more than 90% of the DNA fragments can be ligated and recut.
