  • What is acrylamide gel electrophoresis (SDS-PAGE)?
  • Run and analyze the results of a SDS-PAGE. Polyacrylamide gel electrophoresis (PAGE) is probably the most common analytical technique used to separate and characterize proteins. A solution of acrylamide and bisacrylamide is polymerized. Acrylamide alone forms linear polymers. The bisacrylamide introduces crosslinks between polyacrylamide chains.
  • What is an ionic polyacrylamide flocculant?
  • DESCRIPTION: Anionic polyacrylamide flocculant, viscosity builder/shale inhibitor for mineral and mining applications. EMERGENCY OVERVIEW: White, free flowing dry powder with little or no odor. Spills are very slippery. Avoid contact with skin, eyes and clothing. Contact with eyes may produce irritation and/or redness.
  • How to make acrylamide polymer?
  • For the gel solution, acrylamide is mixed as gel-former (usually 4% V/V in the stacking gel and 10-12 % in the separating gel), methylenebisacrylamide as a cross-linker, stacking or separating gel buffer, water and SDS. By adding the catalyst TEMED and the radical initiator ammonium persulfate (APS) the polymerisation is started.
  • How does bisacrylamide affect pore size?
  • The bisacrylamide introduces crosslinks between polyacrylamide chains. The 'pore size' is determined by the ratio of acrylamide to bisacrylamide, and by the concentration of acrylamide. A high ratio of bisacrylamide to acrylamide and a high acrylamide concentration cause low electrophoretic mobility.
