  • 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 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 is polyacrylamide gel electrophoresis (SDS-PAGE)?
  • The principle and method of polyacrylamide gel electrophoresis (SDS-PAGE). SDS-PAGE is an analytical technique to separate proteins based on their molecular weight.
  • Can polyacrylamide be used for protein separation?
  • For protein separation, virtually all methods use polyacrylamide as an anticonvective, sieving matrix covering a protein size range of 5–250 kD. Some less common applications such as immunoelectrophoresis and the separation of large proteins or protein complexes >300 kD rely on the larger pore sizes of agarose gels.
