LITERATURE
repetitive freezing and thawing or prolonged dialysis produces a loss of enzyme activity
-
the stability of the enzyme depends on the salt concentration. The maximum stability is found in the presence of 3.6 M NaCl
-
unstable in crude extracts and in solutions below pH 7
-
when the enzyme is dialysed against a 50 mM phosphate buffer, pH 7.0, containing 20% glycerol, the enzyme can be stored for 2 weeks without any significant loss of activity
