  • What is polyacrylamide gel electrophoresis (PAGE)?
  • To follow this article, as basic understanding of protein biochemistry is helpful. Polyacrylamide gel electrophoresis (PAGE) is a technique use almost universally in life science laboratories. The goal of this technique is to separate a mixed sample of proteins to identify and quantify single proteins from the mixture.
  • What is a gradient gel for denaturing protein electrophoresis?
  • Gradient gels for denaturing protein electrophoresis feature a gradually increasing polyacrylamide layer from the top (4%) to the bottom (15%) of the gel. A decreasing pore size can allow greater resolution when separating a wide range of protein molecular weights.
  • What is acrylamide gel electrophoresis?
  • Acrylamide Gel Electrophoresis Polyacrylamide gel electrophoresis provides very high resolution of DNA molecules 10–3,000 bp long. Under the appropriate conditions, DNA molecules differing in size by only a single base pair can be resolved (learn more: Nucleic acid electrophoresis education ).
  • Why do we use polyacrylamide instead of agarose?
  • In PAGE, rather than agarose, we use a chemical called polyacrylamide. Varying the percentage of polyacrylamide in the gel lets us change the size of the pores in the gel, which means that we can separate different sizes of protein in different percentage gels. Typical gel percentages are shown in the table below.
