Gel electrophoresis experiments were divided into polyacrylamide gel electrophoresis and agarose gel electrophoresis. Polyacrylamide gel electrophoresis is widely used to separate proteins and smaller molecules of nucleic acids. Agarose gel has larger pore size and is suitable for separating isozymes and their subtypes. Polyacrylamide gel electrophoresis is suitable for the separation of small fragment (5~500bp) DNA, and its resolution is very high.<br>
