  • What is polyacrylamide gel electrophoresis?
  • Polyacrylamide gel electrophoresis (PAGE) is usually used for proteins and smaller DNA fragments. Polyacrylamide gels form by chemical reaction and have uniform pore sizes. They can be cast by the user or purchased as ready-to-use or pre-cast gels. Agarose gels contain natural polysaccharide polymers from seaweed and have irregular pore sizes.
  • What type of gel is used for electrophoresis?
  • Electrophoresis gels are typically agarose or polyacrylamide; each is suited to different molecules. Polyacrylamide gel electrophoresis (PAGE) is usually used for proteins and smaller DNA fragments. Polyacrylamide gels form by chemical reaction and have uniform pore sizes. They can be cast by the user or purchased as ready-to-use or pre-cast gels.
  • Why is polyacrylamide better than agarose?
  • The pores formed in polyacrylamide are smaller than those of agarose, used for agarose gel electrophoresis. This makes it more suitable for the separation of proteins over large polynucleotide DNA or RNA fragments and allows the separation of relatively small proteins.
  • Which acrylamide kits are available for hand casting polyacrylamide gels?
  • Acrylamide powders, premixed acrylamide/bis powders, and premixed acrylamide/bis solutions are offered for handcasting polyacrylamide gels. Standard and alternative cross-linkers and catalysts are available. TGX FastCast acrylamide kits for hand casting polyacrylamide gels enable fast, easy casting and produce long-life gels.
