  • 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 polyacrylamide gel electrophoresis?
  • Different separation media and mechanisms allow subsets of these molecules to be separated more effectively by exploiting their physical characteristics. For proteins in particular, polyacrylamide gel electrophoresis (PAGE) is often the technique of choice. What is polyacrylamide gel electrophoresis and what is protein electrophoresis?
  • How are polyacrylamide gels made?
  • Polyacrylamide gels are cast using mixtures of acrylamide monomers with a cross-linking reagent, usually N,N'-methylenebisacrylamide (bis), both solubilized in buffer Relative distance a protein has traveled compared to the distance traveled by the ion front. This value is used to compare proteins in different lanes and even in different gels.
  • How are polyacrylamide gels characterized?
  • Polyacrylamide gels are characterized by two parameters: total monomer concentration (%T, in g/100 ml) and weight percentage of crosslinker (%C). By varying these two parameters, the pore size of the gel can be optimized to yield the best separation and resolution for the proteins of interest.
