  • Polyacrylamide Gel Electrophoresis (Theory) :

    Theory . PAGE (Polyacrylamide Gel Electrophoresis), is an analytical method used to separate components of a protein mixture based on their size. The technique is based upon the principle that a charged molecule will migrate in an electric field towards an electrode with opposite sign.The general electrophoresis techniques cannot be used to ...

    2018-3-5  Polyacrylamide Gel Electrophoresis (PAGE) When electrophoresis is performed in acrylamide or agarose gels, the gel serves as a size-selective sieve during separation. As proteins move through a gel in response to an electric field, the gel’s pore structure allows smaller proteins to travel more rapidly than larger proteins (Figure 2.1).

  • Polyacrylamide Gel Electrophoresis Science

    Polyacrylamide gel electrophoresis (PAGE) provides a versatile, gentle, high resolution method for fractionation and physical-chemical characterization of molecules on the basis of size, conformation, and net charge. The polymerization reaction can be rigorously controlled to provide uniform gels of reproducible, measurable pore size over a wide range.
