Staining in gel electrophoresis is typically done after the DNA or protein bands have been separated in the gel. The gel is first soaked in a staining solution that binds to the DNA or protein molecules, making them visible under UV light or by using a specialized imaging system. Common staining methods include using ethidium bromide for DNA or Coomassie blue for proteins. After staining, the gel is destained to remove excess dye and improve the contrast of the bands. **
