3.5.1.22 | -20°C 20 mM potassium phosphate pH 7, enzyme is made accessible to substrates by freezing and thawing four times, decrease of activity 20% per round of freezing and thawing, frozen enzyme retains activity for at least 2 years |
3.5.1.22 | -20°C 35 mM potassium phosphate, pH 6.8 |
3.5.1.22 | -20°C enzyme is stable frozen, but loses activity in solution at 0°C in a few days |
3.5.1.22 | -20°C, 5 mM K2SO4, repeated cycles of freezing and thawing inactivate the enzyme |
3.5.1.22 | 2°C 5 mM K2SO4, 1 week, activity dimished to 50% |
