Purifying YAC DNA from PFGE gels

[Andy Grierson]

Hi

We are hoping to extract high enough quality YAC DNA (pure) from PFGE gels for
subsequent restriction digestion.  Contemporary proeedure (apparently) is to
make a total library of yeast and YAC DNA, screen with COT-1, and pick these
clones.  This seems a considerable amount of work.  

So are there any decent protocols that get around this.  How about Agarase (or
is that only for LMP agarose).

Any helpfull comments appreciated

Cheers
