Hello,

You can take a puc-vector with an BamHI Insert in it.
Then you can cut with SmaI (in the MCS) and then with BamHI. This should
cut the distant BamHI-site in the MCS. If the Bam-site near the Sma-site
is cut does not matter. You can then separate Insert and Bam-Sma-cut
vector and insert by electrophoresis and elute the vector.

good luck,
