This is an easy and straightforward protocol that gives efficiencies of 106 to 107 cfu/mg of plasmid DNA. A growth curve is required for each strain that is prepared.

Rapid Elution of DNA Agarose Gels Protocol. This method allows quick purification of DNA fragments from agarose gels for use in cloning and other reactions. Higher yields of purified DNA can be obtained from commercially available purification kits, however greater ligation efficiencies per given amount of DNA have been seen with the use of these described spin columns.

The protocol gives general considerations for the design of targeting vectors for transgenic mice. The protocol shares tips in the design of knock-out and knock-in vectors and some of their strategies for producing homologously recombined embryonic stem cells.
