Proteins in an electrophoresis gel tray being studied by a researcher. These are used to study the proteins in an organism. Electrophoresis is applied in agriculture and biology generally to establish the genetic composition of different organisms. An electrical current is passed through the gel causing different proteins to move at different speeds, thereby isolating one protein from another.
