EC Number   |
Storage Stability |
|---|
    2.7.2.4 | -10°C, can be stored over a period of 6 months with a 40% loss of activity, longer storage does not lead to further inactivation |
| 2.7.2.4 | -15°C, aspartokinase II, stable in buffer containing 20% glycerol, remaining 100% active and homogenous for several months |
| 2.7.2.4 | -15°C, diluted with glycerol to a final concentration of 40%, no loss of enzyme activity observed over a period of more than 1 year |
| 2.7.2.4 | -15°C, dissolved in 0.05 M TES buffer containing 30% glycerol, pH 8.0, activity remains unchanged after 2.5 months |
| 2.7.2.4 | -20°C, appears to be stable over a period of several months' storage |
| 2.7.2.4 | -20°C, can be stored without any noticeable loss in activity |
| 2.7.2.4 | -20°C, storage of the enzyme in the frozen state followed by subsequent thawing leads to a rapid decline in activity |
| 2.7.2.4 | -70°C, stored in buffer containing 200 mM KCl and 2 mg/ml bovine serum albumin, stable for more than 1 year |
| 2.7.2.4 | -80°C, 150 mM KCl, 20 mM Tris HCl, pH 7.4 |
| 2.7.2.4 | -80°C, HEPES buffer, pH 7.5, 1 mM Lys, 10% (v/v) glycerol, several month, without any loss of activity |
