Hi!
today we discovered an old solution of penicillin-amidase from E.coli
(EC 3.5.1.11) in our fridge. It was stored there for about 4 months at
-4°C. (I don't know who put it there!!!) At this temperature it is
liquid. The supplier specifies that the enzyme is to stored below -18°C,
where the solution is freezed.
Does anybody know whether this solution is still OK?
