There are two common types of gel: polyacrylamide and agarose. For most applications, denaturing acrylamide gels are most appropriate.

In certain circumstances, e.g., resolving different conformers of RNAs or RNA-protein complexes, native gels are ...
Get Price2018-3-5 · 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).
