I don't know this vector, but I guess that the point of using BstX-I is
that both ends after digestion are not compatible. That is also the
reason why they put two BstX-I instead of one. So your test is fairly
simple - if you don't have many colonies after Vector + Ligase control,
then you have complete digest.
