LITERATURE
-20°C, 30% of the original activity remains after 6 months
-
-20°C, 50 mM potassium phosphate buffer, pH 7.4, stable for at least 2 weeks

-20°C, stable for at least 2 years
-
-80°C, HEPES buffer, pH 7.25, 500 mM NaCl, 5% glycerol, 2 mM DTT, 0.025% sodium azide
-80°C, triethanolamine (100 mM, pH 7.5), containing 1.0 mM beta-mercaptoethanol, 1.0 mM EDTA, 30 mM sodium arsenate heptahydrate, 1.0 mM phenylmethylsulfonyl fluoride, 50 mM NAD+, 1.0 mM pepstatin, 1.0 mM leupeptin, 0.5 M KCl, and glycerol 10% (v/v), 8 months, 1% loss of activity
-
0-4°C, no substantial loss of activity after several months
-
25°C, free enzyme in Tris-HCl (50 mM, pH 8.6), containing 1.0 mM beta-mercaptoethanol, 30 mM sodium arsenate heptahydrate, and 1.0 mM EDTA, 99% of the enzymatic activity is retained after 24 h and 57% after 120 h
-
2°C, stable for several months
-
4°C, 1 mM EDTA, 75% glycerol, stable
-
4°C, crystalline suspension in 67% saturated ammonium sulfate containing EDTA, KCN, and dithioerythritol is stable for many months
-
4°C, free enzyme in buffer 8, 55% of the enzymatic activity is retained after dialysis and after 48 h the calculated activity has fallen to 7%
-
4°C, free enzyme in Tris-HCl (50 mM, pH 8.6), containing 1.0 mM beta-mercaptoethanol, 30 mM sodium arsenate heptahydrate, and 1.0 mM EDTA, 55% of the enzymatic activity is retained after dialysis and after 48 h the calculated activity has fallen to 25%
-
4°C, in 67% saturated ammonium sulfate solution containing EDTA and dithiothreitol, stable for months
-
4°C, pentalenolactone-insensitive enzyme stable up to 6 months. Pentalenolactone-sensitive enzyme loses activity with a half-life of 7 days
-
5°C, stable for several months
-
after 6 months of storage, the specific activity of hGAPDH decreases to 10-15% of the original value due to the reversible oxidation of the enzyme. Reactivation of the enzyme by dissolving in 10 mM potassium phosphate, pH 7.4, and 5 mM DTT, to 1 mg/ml concentration, 2-4 h of incubation at 20-25°C, the specific activity of hGAPDH increases 5-7-fold. Alternatively, the enzyme can be dialyzed against required buffer solution containing 5 mM DTT
at -20°C storage after dialysis following the first (NH4)2SO4 fractionation step during purification, normal muscle and leukocyte enzyme is stable. Enzyme from chronic myeloid leukemia patients and sarcoma tissue loses about 80% of activity.
