thermal stability of the enzyme is increased by means of dextran-modification or addition of chelating reagents at high concentrations
pH 9, 10 min, nonconjugated enzyme is completely inactivated, enzyme conjugated with dextran retains 28% of its activity, 17% loss of activity in presence of 100 mM EDTA, 27% loss of activity in presence of 50 mM trans-1,2-diaminocyclohexane-N,N,N‘,N‘-tetracetic acid, 16% loss of activity in presence of 100 mM citric acid, 50% loss of activity in presence of 50 mM malic acid, 51% loss of activity in presence of 50 mM itaconic acid, 33% loss of activity in presence of 50 mM Mg*EDTA
at pH 7.2, half-life: 25 min without added NAD+, half-life: 35 min including added NAD+, at pH 8.5: activity more rapidly lost
