All of us in our lab doing cloning are experiencing problems with ligation
reactions.  We have used two ligases but we may have used one improperly.
Therefore, we would like to ask a question about the other: has anyone had any
problems with USB DNA particular lot #200970?  (However, we have
had problems with some of the other lots that we purchased)
