  • What is polyacrylamide gel electrophoresis (PAGE)?
  • The polyacrylamide gel electrophoresis (PAGE) method to separate individual MNCs with improved monodispersity is highly significant. In 1972, Joseph Sambrook, Phillip Sharp and William Sugden created a biotechnique called gel electrophoresis for separating and visualizing DNA fragments.
  • 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.
  • 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).
  • What happens when polyacrylamide and bis-acrylamide crosslink?
  • By crosslinking polyacrylamide and bis-acrylamide, a network of pores is formed in the gel. Due to the pore size, molecules can be sorted via the gel matrix. Gel pore size depends on the concentration of monomers (% T).
