  • What is polyacrylamide gel electrophoresis (PAGE)?
  • Introduction Polyacrylamide gel electrophoresis (PAGE) is one of the most widely used methods to analyze proteins biochemically [ 1 ]. After separation by electrophoresis, protein bands need to be detected with a subsequent staining step.
  • 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 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.
  • What parameters characterize polyacrylamide gel?
  • Two parameters characterizes polyacrylamide gel: total monomer concentration (% T, in g/100 ml) and weight percentage of crosslinker (%C). Deferring these two parameters, helps in regulation in the pore size of the gel to yield the best separation result. %T indicates the pore size of the prepared gel.
