  • What is polyacrylamide gel electrophoresis (PAGE)?
  • As a well-established electrophoresis technique, polyacrylamide gel electrophoresis (PAGE) is ubiquitously applied to routine protein analyses in biochemistry and molecular biology labs [ , , ].
  • Are polyacrylamide gels better than agarose gels?
  • 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.
  • How much DNA can be applied to a polyacrylamide gel?
  • Up to 10 µg of DNA can be applied to a single slot (1 cm × 1 mm) of a typical polyacrylamide gel without significant loss of resolution. (3) DNA recovered from polyacrylamide gels is extremely pure and can be used for the most demanding purposes (e.g., microinjection of mouse embryos).
  • What is discontinuous polyacrylamide gel electrophoresis?
  • In its original version of discontinuous polyacrylamide gel electrophoresis (Davis, 1964 ), a strategic use of different buffer systems in the gel, in the sample, and in running buffer caused the proteins in the sample to focus into a sharp band before entering the gel.
