the problem on plasmid ligation and transformation

I think you should be concerned about the compatibility of the PCR reaction
mixture with the REs you are using. I would have probably band isolated
*first* and then digested, then putting everything together for the ligation
reaction. The other issue is whether the RE site is too close to the end of
the PCR product.

Adding an extra cloning step (ie. using a TA vector first) is probably the
less problematic though...
