Unit definition :
One Unit is defined as the amount of Acc65 I required to completely digest 1 §¶ of Ad-2 DNA in one hour at 37¡É in 50 §¡ assay mixture.
Typical Reaction Conditions
: Add 5 §¡ of 10X Reaction Buffer 'D'[final conc.: 6 mM Tris-HCl (pH 7.9 @ 37¡É), 6 mM MgCl2, 150 mM NaCl, 1 mM DTT], 1~2 §¡ of DNA(0.5~1.0 §¶/§¡), 5 §¡ of 10X BSA(final conc.: 100 §¶/§¢), 1 §¡ of Acc65 I and 37~38 §¡ of sterile water in 50 §¡ reaction mixture. Incubate at 37¡É.
Heat Inactivation
: 65¡É for 20 min.

Quality control
Overdigestion: The same band pattern as a digestion in one unit of Acc65 I for one hour was showing after incubation of 1 §¶ of Ad-2 DNA with Units of Acc65 I for 16 hr in 50 §¡ of reaction mixture at 37¡É as determined by agarose gel electrophoresis.
Ligation-Recut: After a 10-fold digestion for one hour, % of Ad-2 DNA fragments were ligated with T4 DNA ligase at 16¡É and % of the ligated DNA fragments could be recut with Acc65 I.
