For example, it is used in DNA fingerprinting and the detection of genetic variants and proteins involved in health and disease as well as in the detection and purification of nucleic acids and proteins for research. Gel electrophoresis can provide information about the molecular weights and charges of proteins, the subunit structures of proteins, and the purity of a particular protein preparation. As proteins move through a gel in response to an electric field, the smaller molecules travel more rapidly than larger proteins (see figure below).
