  • 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 [ , , ].
  • Can protein molecular weights be determined by gel electrophoresis?
  • Indeed, the determination of protein molecular weights by SDS gel electrophoresis is currently the preferred method of choice. Therefore, rather than just demonstrating gel electro-phoretic patterns of proteins, this experiment is designed to allow the student to determine the molecular weight of an unknown protein.
  • 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.
