  • What is polyacrylamide gel electrophoresis (PAGE)?
  • Polyacrylamide gel electrophoresis (PAGE) is routinely used for protein analysis, and can also be used to separate nucleic acid fragments smaller than 100 bp. Nucleic acids are usually analyzed using a continuous buffer system where there is a constant buffer composition, pH, and pore size throughout the gel.
  • What is the pore size of polyacrylamide gel electrophoresis?
  • Polyacrylamide gel electrophoresis (PAGE) provided uniform pore size for separation of proteins ranging in size from 5 to 2000 kDa. Pore size of gel is controlled by concentrations of acrylamide and bis-acrylamide used in preparation of gel . There are two types of gels used, namely, stacking gel and separating/resolving gel.
  • 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 blue native polyacrylamide gel electrophoresis?
  • Blue-Native polyacrylamide gel electrophoresis (Blue Native PAGE) was originally introduced by Schagger and von Jagow as a technique for separating enzymatically active membrane protein complexes under mild condition [ 35 ].
