Blunt end ligation debate.

I gotta ask. How do you know that your CIAP step failed? Did you check your
cut ligase-minus vector for colony formation? Maybe you simply didn't get
all of the vector cut in the first place. Even with CIAPing I routinely 2x
gel purify my vector before using it for ligations and it is well worth the
effort. I rarely get more than one or two colonies on my control plate.
