Recognition site | GGGCC↑C C↓CCGGG |
Source | E.coli strain that carries the cloned Apa I gene from Acetobacter pasteurianus |
Assayed on | Lambda DNA (dam-dcm-, BamHI-digest) |
Unit definition | One unit of the enzyme is the amount required to hydrolyze 1 μg of Lambda DNA (dam-dcm-, BamHI-digest) in 1 hour at 37°C in a total reaction volume of 50 μl. |
Reaction buffer | SE-buffer Y + BSA |
Optimal temperature | 37oC |
Storage conditions | 10 mM Tris-HCl (pH 7.5); 200 mM NaCl; 0.1 mM EDTA; 7 mM 2-mercaptoethanol; 200 μg/ml BSA; 50% glycerol. Store at -20°C. |
Ligation | After 50-fold overdigestion with enzyme more than 95% 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 37°C.

Reagents Supplied with Enzyme |
10 X SE-buffer Y, BSA
|
Inactivation 20 minutes under | 65oC |
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.
