FAQ: My CviAII enzyme was working fine several months ago, but now it is not working anymore. Is there a reason?
Compared to most of our other restriction enzymes CviAII is a relatively unstable enzyme, and thus it has a guaranteed shelf life of only a year when properly stored. Please make sure that the enzyme is not passed its expiration date when using it. Also, due to the relative instability of this enzyme, digestions of more than 1 hr are not recommended.
