  • 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.
  • 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 does %t mean in polyacrylamide gel?
  • %T indicates the relative pore size of the resulting polyacrylamide gel: higher %T refers to a larger polymer-to-water ratio and on average smaller pores. The practical ranges for monomer concentration are stock solutions of 30-40%, with different ratios of acrylamide monomer to crosslinker.
  • How are polyacrylamide gels prepared?
  • Polyacrylamide gels are prepared by free radical polymerization of acrylamide and a comonomer crosslinker such as bis-acrylamide. Polymerization is initiated by ammonium persulfate (APS) with tetramethylethylenediamine (TEMED) as the catalyst (see figure below).
