  • 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 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 ).
  • What is a 15% polyacrylamide gel used for?
  • Gels of 15% polyacrylamide are therefore useful for separating proteins in the range of 100,000–10,000. However, a protein of 150,000 for example, would be unable to enter a 15% gel. In this case, a larger-pored gel (e.g., a 10% or even 7.5% gel) would be used so that the protein could now enter the gel, and be stained and identified.
  • When was polyacrylamide gel used in electrophoresis?
  • Polyacrylamide gel (PAG) had been known as a potential embedding medium for sectioning tissues as early as 1964, and two independent groups employed PAG in electrophoresis in 1959. It possesses several electrophoretically desirable features that make it a versatile medium.
