  • 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 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.
  • 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 a polyacrylamide gel made of?
  • The polyacrylamide gel is made of the monomer acrylamide, the crosslinker N,N’-methylene bis-acrylamide, the accelerator N,N,N’,N’-tetramethylethylenediamine (TEMED) and the free radical generator APS. Gel buffer solutions must be stacked and resolved to separate NCs as they move through the porous gel when an applied potential is present.
