  • A Guide to Polyacrylamide Gel Electrophoresis and Detection

    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).
