  • Why is sodium dodecyl sulfate polyacrylamide gel electrophoresis not enough?
  • Because of their similar molecular masses and extensive post-translational modifications, the resolution of current sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS PAGE) is not enough for fine separation of these proteins.
  • Why is acrylamide polymerization slow?
  • Due to protonation and oxidization of TEMED, the polymerization process of acrylamide in acidic condition is not only very slow but also generates mechanistically weak gels. The presence of titanium dioxide nanoparticles provides a substrate to differentially adsorb proteins with different affinities.
  • How is polyacrylamide gel formed?
  • Polyacrylamide gels are usually formed by copolymerization of acrylamide and bis-acrylamide with ammonium persulfate (APS) and tetramethylethylenediamine (TEMED) as the initiator and catalyst. There are mainly three steps for such gel preparation. (A) Initiation of free radicals.
  • What is polyacrylamide gel electrophoresis?
  • Since the invention in last century, polyacrylamide gel electrophoresis remains the most powerful separation technique for proteomics 1, 2, 3 so far. By using this technique, thousands of cellulous proteins can be simultaneously fractionated and displayed with unparalleled high resolution in a gel.
