  • How does polyacrylamide gel electrophoresis (PAGE) work?
  • Gel electrophoresis is a fundamental technique for separating molecules such as DNA, RNA and proteins in laboratories across the biological disciplines. In this article, we will consider how polyacrylamide gel electrophoresis (PAGE) works, how it can be interpreted and some of its applications.
  • 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.
  • 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.
  • What is two-dimensional polyacrylamide gel electrophoresis?
  • Two-dimensional polyacrylamide gel electrophoresis (2D-PAGE) has been used extensively to study changes in expression in cell lines and bulk tissue specimens [28,69,76,109].
