Are solutions of Product C2888, Acetylcholinesterase from Electrophorus electricus (electric eel), harmed by freezing?
1 answer-
Yes, solutions may be harmed by freezing. The data sheet for Product C2888 indicates that solutions stabilized by the addition of BSA are stable when kept refrigerated for up to six months. A customer has reported to us that they tried freezing a solution to which BSA was added; they found that the solution had a 40 percent loss of activity after four months in the freezer. So our best recommendation is that solutions be stabilized with BSA and kept refrigerated, not frozen.
