  • What is polyacrylamide gel?
  • Polyacrylamide gel is a thicker and stickier substance, similar to what’s in baby diapers. (Ashley P. Taylor, Discover Magazine, 7 Sep. 2012)
  • 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.
  • Why is polyacrylamide used for protein separation?
  • Polyacrylamide is ideal for protein separations because it is chemically inert, electrically neutral, hydrophilic, and transparent for optical detection at wavelengths greater than 250 nm. Additionally, the matrix does not interact with the solutes and has a low affinity for common protein stains.
  • How is polyacrylamide produced?
  • Polyacrylamide is produced from monomers of acrylamide in a reaction initiated by free radicals generated by reduction of ammonium persulfate by TEMED (N, N, N ’, N ’-tetramethylene diamine). These linear strands of polyacrylamide form into a gel after cross-linkage by N, N ’-methylenebisacrylamide.
