  • What is polyacrylamide gel electrophoresis (PAGE)?
  • Polyacrylamide gel electrophoresis (PAGE) provides a versatile, gentle, high resolution method for fractionation and physical-chemical characterization of molecules on the basis of size, conformation, and net charge.
  • 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.
  • Can polyacrylamide be used as electrically neutral gel?
  • Cross-linked chains of polyacrylamide can be used as electrically neutral gels to separate double-stranded DNA fragments according to size and single-stranded DNAs according to size and conformation.
  • 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).
