  • What is polyacrylamide gel electrophoresis (PAGE)?
  • Polyacrylamide gel electrophoresis (PAGE) is a quick and sensitive method for analyzing the composition of mixtures of proteins. Since the early 1970s, this method has become a routine and frequently used analytical procedure in all protein chemistry laboratories, and as such, biology students should of course be familiar with this basic technique.
  • What is electrophoresis using agarose or polyacrylamide gels?
  • Policies and ethics Electrophoresis through agarose or polyacrylamide gels is a standard method used to separate, identify, and purify nucleic acids. The technique is simple, rapid to perform and capable of resolving fragments that differ by as little as 0.2% in size.
  • What is acrylamide gel electrophoresis?
  • The basic theory behind SDS gel electrophoresis is as follows: Polyacrylamide gel electrophoresis utilizes a cross-linked acrylamide support through which the protein samples are electrophoresed. The acrylamide gel is formed from acrylamide monomer and ‘bis’-acrylamide, which provides the crosslinking between monomer chains (Fig. 1).
  • When was polyacrylamide gel used in electrophoresis?
  • Polyacrylamide gel (PAG) had been known as a potential embedding medium for sectioning tissues as early as 1964, and two independent groups employed PAG in electrophoresis in 1959. It possesses several electrophoretically desirable features that make it a versatile medium.
