5'… CAC▼GTC …3'
3'… GTG▲CAG …5'
Source Bacillus stearothermophilus SE-U62
Optimal buffer SE-buffer O
Optimal temperature 60 °C
Inactivation temperature 80 °C

BGOWYROSE
75751007575100
Unit definition One unit of the enzyme is the amount required to hydrolyze 1 μg of Lambda DNA in 1 hour at 60°C in a total reaction volume of 50 μl.
Assayed on Lambda DNA
Storage conditions 10 mM Tris-HCl (pH 7.5); 50 mM KCl; 0,1 mM EDTA; 7 mM 2-mercaptoethanol; 200 μg/ml BSA; and 50% glycerol; Store at -20°C.
Ligation After 3-fold overdigestion with enzyme 80% of DNA fragments can be ligated. Of these 90% can be recut.
Nonspecific hydrolysis No nonspecific activity was detected after incubation of 1 μg of Lambda DNA with 5 u.a. of enzyme for 16 hours at 60°C.
Methylation sensitivity not tested
Supplied with enzyme 10 X SE-buffer O, BSA
Notes High enzyme concentration may result in star activity. To obtain 100% activity, BSA should be added to the 1 x reaction mix to a final concentration of 100 μg/ml. Do not use BSA for long incubation.
