General Stability

General Stability on EC - carbonyl reductase (NADPH)

Please wait a moment until all data is loaded. This message will disappear when all data is loaded.
activation by arachidonic acid leads to a decrease in thermal stability
an ammonium sulfate precipitate (3 M, pH 7) of the enzyme loses its activity completely within a few days
compared to activity in acetate and Tris-HCl, carbonyl reductase shows higher activity using potassium phosphate as buffer at pH 5.5 or pH 7
glycerol, 20% v/v, stabilizes
minor loss of activity in 50 mM phosphate buffer is observed during purification and storage at 4C without additional precautions
no conditions to stabilize the enzyme by freezing at -20C are found. Addition of 1-10% bovine serum albumin, 20-50% glycerol, 20% 1,2-ethanediol or 0.1% Triton X-100 to the enzyme solution in 40 mM phosphate or 40 mM Tris-HC1 pH 7 before freezing for 1 day or longer has no stabilizing effect
