  • 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
  • What is a polyacrylamide gel?
  • Polyacrylamide gels are chemically cross-linked gels formed by the polymerization of acrylamide with a cross-linking agent, usually N,N’-methylenebisacrylamide. The reaction is a free radical polymerization, usually carried out with ammonium persulfate as the initiator and N,N,N’,N’-tetramethylethylendiamine (TEMED) as the catalyst.
  • 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).
  • What is polyacrylamide gel electrophoresis (SDS-PAGE)?
  • The most commonly used form of polyacrylamide gel electrophoresis is the Sodium dodecyl suplhate Polyacrylamide gel electrophoresis (SDS- PAGE) used mostly for the separation of proteins. SDS-PAGE (Polyacrylamide Gel Electrophoresis), is an analytical method used to separate components of a protein mixture based on their size.
