Storage conditions<\/strong>: 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<\/strong>:
After 10-fold overdigestion with enzyme more than 90% of the DNA fragments can be ligated and recut.
Non-specific hydrolisis<\/strong>:
No nonspecific activity was detected after incubation of 1 μg of Lambda DNA with 20 u.a. of enzyme for 16 hours at 37°C.<\/td>\n<\/tr>\n

Reagents Supplied with Enzyme<\/b><\/td>\n10 X SE-buffer W, BSA
Reagents Supplied with Enzyme<\/strong>:
Methylation sensitivity<\/strong>: not tested
Notes:<\/strong> To obtain 100% activity, BSA should be added to the 1x reaction mix to a final concentration of 100 μg\/ml.
Do not use BSA for long incubation.
