John, I am having that very problem. I am trying to do a ligation and 
well, there is a still a lot of uncut vector. If you do use PAGE, then 
don't you have to do the crush and soak method of DNA purification. Right 
ow, I just run it out on the gel and cut the band out, leaving it in the 
LM agarose. 

Help, I am at my wit's end trying to do this damn ligation. Thanks,
