0107510010100
Unit definition One unit of the enzyme is the amount required to hydrolyze 1 μg of Lambda DNA (dam-) in 1 hour at 37°C in a total reaction volume of 50 μl.
Assayed on Lambda DNA (dam-)
Storage conditions 10 mM Tris-HCl (pH 7.5); 250 mM NaCl; 0.1 mM EDTA; 7 mM 2-mercaptoethanol; 50% glycerol; Store at -20°C.
Ligation After 5-fold overdigestion with enzyme about 50% of the DNA fragments can be ligated and 90% of them can be recut. In the presence of 10% PEG
Nonspecific hydrolysis No nonspecific activity was detected after incubation of 1 μg of Lambda DNA with 10 u.a. of enzyme for 16 hours at 37°C.
Methylation sensitivity Blocked by overlapping Dam methylation (G m ATC) TCGC GA TC.
Supplied with enzyme 10 X SE-buffer W
