  • What is polyacrylamide gel electrophoresis?
  • Different separation media and mechanisms allow subsets of these molecules to be separated more effectively by exploiting their physical characteristics. For proteins in particular, polyacrylamide gel electrophoresis (PAGE) is often the technique of choice. What is polyacrylamide gel electrophoresis and what is protein electrophoresis?
  • How does a polyacrylamide gel separate analytes?
  • The basic principle of PAGE is to separate analytes by passing them through the pores of a polyacrylamide gel using an electric current. To achieve this, an acrylamide– bisacrylamide mix is polymerized (polyacrylamide) by the addition of ammonium persulfate (APS).
  • What is a polyacrylamide gel used for?
  • The preparation of the polyacrylamide gels (PAGE) is carried out in a free radical fashion. The gels prepared are used in the biochemical field for the separation of proteins, DNA fragments, RNA, and other macromolecules. PAGE gels tend to have a higher resolving power than agarose or starch gels in specific situations. 34.3. Polyacrylates
  • How are proteins extracted from polyacrylamide gels?
  • In this Tech Tip, various methods of extraction (elution) of proteins from polyacrylamide gels are described. The first step in purifying a protein from a polyacrylamide gel is to locate the electrophoresed protein of interest in the gel. There are two options for band identification:
