Activity in SEBuffers:

SEBuffer B            25 - 50%

SEBuffer G           50 - 75%

SEBuffer O           50 - 75%

SEBuffer W                100%

SEBuffer Y           75 -100%

SEBuffer ROSE         100%

When using a buffer other than the optimal (suppied) SEBuffer, it may be necessary to add more enzyme to achieve complete digestion. 

Optimal temperature: 55°C

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.

Ligation: After 50-fold overdigestion with enzyme more than 90% of the DNA fragments can be ligated and recut.

Non-specific hydrolisis: No nonspecific activity was detected after incubation of 1 μg of Lambda DNA with 100 u.a. of enzyme for 16 hours at 55°C.

Reagents Supplied with Enzyme: 10 X SE-buffer W, BSA

Methylation sensitivity: not tested

Inactivation: 20 minutes under 65°C

Notes: 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.
