Recognition Sequence :
CC↑TNAGG
GGANT↓CC
Unit Definition :
One unit of the enzyme is the amount required to hydrolyze 1 μg of Lambda DNA (HindIII-digest) in 1 hour at 37°C in a total reaction volume of 50 μl.
Reaction Temperature :
37°C
Storage Buffer :
10 mM KH2PO4 (pH 7.4); 50 mM KCl; 0.1 mM EDTA; 7 mM 2-mercaptoethanol; 200 μg/ml BSA; 50% glycerol.
Ligation :
After 2-fold overdigestion with enzyme about 50% of DNA fragments can be ligated by using of high concentration T4 DNA ligase with presence of 10% PEG. Of these more than 90% can be recut.
