LITERATURE
25 cycles of freezing/thawing cause 40% loss of activity
-
detergents, e.g. Brij 58, Triton X-100, cholate, deoxycholate or beta-octylglucoside stabilize
-
glycerol, 30%, stabilizes partially purified enzyme
-
high instability of the enzyme once it is removed from the inner mitochondrial membrane
repeated freezing and thawing: rapid loss of activity
