Run a larger gel (more distance between the + and - ends) overnight with 3% agarose. You could also try a polyacrylamide gel as well, but I don't have experience running one for that purpose. If its appropriate I'm sure someone will suggest the proper % and setup apparatus.

I am trying to separate 745bp, 646bp, and 655bp fragments on an
agarose gel. I've separated the 745bp fragment but the other two
fragments are not separating on a 2.5% agarose gel, running at 55V for
3.5 hours. I also want a crisp band because I am planning to cut these
fragments out and extract the DNA for sequencing. Any suggestions?
