  • What is polyacrylamide gel electrophoresis (PAGE)?
  • As a well-established electrophoresis technique, polyacrylamide gel electrophoresis (PAGE) is ubiquitously applied to routine protein analyses in biochemistry and molecular biology labs [ , , ].
  • How do proteins migrate in polyacrylamide gel electrophoresis?
  • In polyacrylamide gel electrophoresis, proteins migrate in response to an electrical field through pores in a polyacrylamide gel matrix; pore size decreases with increasing acrylamide concentration. The combination of pore size and protein charge, size, and shape determines the migration rate of the protein.
  • What is acrylamide gel electrophoresis?
  • The basic theory behind SDS gel electrophoresis is as follows: Polyacrylamide gel electrophoresis utilizes a cross-linked acrylamide support through which the protein samples are electrophoresed. The acrylamide gel is formed from acrylamide monomer and ‘bis’-acrylamide, which provides the crosslinking between monomer chains (Fig. 1).
  • 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.
