LITERATURE
-10°C, overnight, in a saturated (NH4)2SO4 solution, approximately 20% loss of activity
-
-18°C, stable for several months
-70°C, stable for several months
-
2°C, several days, maintains well over 50% of its activity
-
4°C, 80-90% loss of activity after 60 h
-
4°C, in presence of 0.1 mM UDP and 1 mM DTT, 3 days, 20% loss of activity
-
4°C, purified enzyme expressed in insect cells, stable
-
4°C, purified enzyme is 80% pure, no further purification because it is unstable to freezing and has limited stability upon storage at 4°C
