  • Polyacrylamide Gel Electrophoresis - CSH Protocols

    Polyacrylamide gels have the following three major advantages over agarose gels: (1) Their resolving power is so great that they can separate molecules of DNA whose lengths differ by as little as 0.1% (i.e., 1 bp in 1000 bp). (2) They can accommodate much larger quantities of DNA than agarose gels. Up to 10 µg of DNA can be applied to a single ...
