  • What is the principle of polyacrylamide gel electrophoresis?
  • Polyacrylamide gel electrophoresis is based on the principle that charged particles migrate to the electrode of the opposite sign under the influence of an electric field. Principle of polyacrylamide gel electrophoresis, Image source: DOI: 10.1016/B978-0-12-803077-6.00012-6
  • How does a polyacrylamide gel separate analytes?
  • The basic principle of PAGE is to separate analytes by passing them through the pores of a polyacrylamide gel using an electric current. To achieve this, an acrylamide– bisacrylamide mix is polymerized (polyacrylamide) by the addition of ammonium persulfate (APS).
  • How is polyacrylamide used in molecular biology?
  • Polyacrylamide is also often used in molecular biology applications as a medium for electrophoresis of proteins and nucleic acids in a technique known as PAGE. PAGE was first used in a laboratory setting in the early 1950s.
  • How does polyacrylamide gel form?
  • The polyacrylamide gel forms by polymerizing acrylamide and a crosslinking agent, i.e., N, N’-methylene-bis-acrylamide. It does not react with proteins and consists of pores and channels that allow the protein to move through it.
