  • What is polyacrylamide gel?
  • Related Topics: Protein Standards, Buffer Systems and Gel Chemistries, and Handcasting Polyacrylamide Gels. Polyacrylamide gels are prepared by free radical polymerization of acrylamide and a comonomer crosslinker such as bis-acrylamide.
  • 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 is acrylamide polymerized?
  • To achieve this, an acrylamide– bisacrylamide mix is polymerized (polyacrylamide) by the addition of ammonium persulfate (APS). The reaction, which is catalyzed by tetramethylethylenediamine (TEMED), forms a net like structure with pores through which analytes can move (Figure 2).
  • Are polyacrylamide gels homogeneous?
  • Polyacrylamide gels have the great advantage of being almost completely homogeneous, and adsorption and electro-osmosis do not play a major role in the electrophoresis (see e.g. Maurer, 1971).
