  • What is two dimensional polyacrylamide gel electrophoresis?
  • This review discusses the principles of 2-DE as well as both recent methodological advances and new applications. Two dimensional polyacrylamide gel electrophoresis (2-DE) is considered a powerful tool used for separation and fractionation of complex protein mixtures from tissues, cells, or other biological samples.
  • 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 a two dimensional gel electrophoresis?
  • The original two-dimensional gel electrophoresis format was developed almost 30 years ago (1) to exploit this variation in protein charge and size for separation purposes. The isoelectric point of a protein (pI) is the pH at which it has a net zero charge, which, for the majority of proteins, lies between pH 4.0 and 8.0.
  • Why is polyacrylamide better than agarose?
  • The pores formed in polyacrylamide are smaller than those of agarose, used for agarose gel electrophoresis. This makes it more suitable for the separation of proteins over large polynucleotide DNA or RNA fragments and allows the separation of relatively small proteins.
