  • How does polyacrylamide gel electrophoresis (PAGE) work?
  • Gel electrophoresis is a fundamental technique for separating molecules such as DNA, RNA and proteins in laboratories across the biological disciplines. In this article, we will consider how polyacrylamide gel electrophoresis (PAGE) works, how it can be interpreted and some of its applications.
  • 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.
  • How do you perform a nondenaturing polyacrylamide gel electrophoresis?
  • 10. Connect the electrodes to a power pack, turn on the power, and begin the electrophoresis run. Nondenaturing polyacrylamide gels are usually run at voltages between 1 V/cm and 8 V/cm.
