  • 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 the difference between agarose gel and polyacrylamide gel electrophoresis?
  • In polyacrylamide gel electrophoresis, polyacrylamide gel separates macromolecules, i.e., proteins of size five kDa to 250 kDa. Similarly, it can also isolate DNA of 5- 500 bp size. In agarose gel electrophoresis, agarose gel separates DNA, RNA, and protein. It can isolate DNA about 50-20,000 bp in size.
  • Why is polyacrylamide gel electrophoresis useful in HIV testing?
  • PAGE is helpful to analyze the size and number of polypeptide subunits. It is useful in HIV tests to separate HIV protein. Polyacrylamide gel electrophoresis consists of the following benefits:
  • 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.
