Assayed onLambda DNA (HindIII-digest)
Unit definitionOne unit of the enzyme is the amount required to hydrolyze 1 μg of Lambda DNA (HindIII-digest) 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 (%)
BGOWYRose
50 - 7550 - 7510 - 2525 - 5010040
Optimal temperature
37oC
Storage conditions10 mM KH2PO4 (pH 7.4); 50 mM KCl; 0.1 mM EDTA; 7 mM 2-mercaptoethanol; 200 μg/ml BSA; 50% glycerol. Store at -20°C.
LigationsAfter 2-fold overdigestion with enzyme about 50% of DNA fragments can be ligated by using of high concentration T4 DNA ligase with presence of 10% PEG. Of these more than 90% can be recut.
Non-specific hydrolisisNo nonspecific activity was detected after incubation of 1 μg of Lambda DNA with 30 u.a. of enzyme for 16 hours at 37°C.
