Source: An E.coli strain, that carries the cloned gene Tth111I from Thermus Thermophilus 111
Unit definition:
One unit of the enzyme is the amount required to hydrolyze 1 μg of Lambda DNA (HindIII-digest) in 1 hour at 65°C in a total reaction volume of 50 μl.
Assayed on:
Lambda DNA (HindIII-digest)
Optimal SE-buffer: SE-buffer Y
Enzyme activity (%):
B | G | O | W | Y | ROSE |
75 | 50 | 10 | 10 | 100 | 100 |
Storage conditions: 10 mM Tris-HCl (pH 7.5); 500 mM NaCl; 0,1 mM EDTA; 1 mM DTT; 50% glycerol. Store at -20°C.
Ligations:
After 2-fold overdigestion with enzyme 10% of the DNA fragments can be ligated.
Non-specific hydrolisis:
No nonspecific activity was detected after incubation of 1 μg of Lambda DNA with 5 u.a. of enzyme for 16 hours at 65°C.
Reagents Supplied with Enzyme:
Methylation sensitivity: not tested
Notes: High enzyme concentrationmay result in star activity.
