  • 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.
  • What is polyacrylamide gel electrophoresis?
  • Polyacrylamide gel electrophoresis, popularly known by its acronym PAGE is an analytical technique which is based on the principle of migration of charged particles under the influence of electrical field. The main purpose of this technique in analytical chemistry is to separate the mixture of protein or nucleic acid based on their size.
  • 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).
  • Does polyacrylamide gel electrophoresis identify thiol-protected gold nanoclusters?
  • Polyacrylamide gel electrophoresis separation and identification of various thiol-protected gold nanoclusters. PAGE separation of Au nanoclusters stabilized with (A) SG, (B) (PG)SH, (C) (SA)SH and their negative-ion ESI mass spectra and optical absorption spectra of Au:S (PG) (1–6) and Au:S (SA) (7 and 8) clusters.
