Definition of Gel electrophoresis
Gel electrophoresis is a method for the separation and analysis of macromolecules (DNA, RNA and protein) based on size and charge. There are two different types of gels commonly used agarose and polyacrylamide gels.
1D electrophoresis is performed on nucleic acids and proteins whereas, 2D electrophoresis is for separating protein based on size and pH.
