Reaction buffer:
GM-buffer Y + BSA, (33 mM Tris-acetate (pH 7.9 at 25°C); 10 mM magnesium acetate; 66 mM potassium acetate; 1 mM DTT + 100 μg/ml BSA .)

Storage conditions:
10 mM Tris-HCl (pH 7.5); 50 mM KCl; 0.1 mM EDTA; 7 mM 2-mercaptoethanol; 200 µg/ml BSA; 50% glycerol.

Storage temperature:
-20°C

Ligation:
After 2-fold overdigestion with enzyme more than 70% of DNA fragments can be ligated. Of these 80% can be recut. In the presense of 10% PEG ligation is better.

Non-specific hydrolysis:
No nonspecific activity was detected after incubation of 1 μg of DNA with 2 u.a. of enzyme for 16 hours at 30°C.

Optimum temperature:
30°C

Inactivation 20 minutes:
under 65°C
