After the electrophoresis is complete, the molecules in the gel can be [[staining (biology)|stained]] to make them visible. DNA may be visualized using [[ethidium bromide]] which, when intercalated into DNA, [[fluorescence|fluoresce]] under [[ultraviolet]] light, while protein may be visualised using [[silver stain]] or [[Coomassie brilliant blue]] dye. Other methods may also be used to visualize the separation of the mixture's components on the gel. If the molecules to be separated contain [[radioactivity]], for example in a [[DNA sequencing]] gel, an [[isotopic tracer|autoradiogram]] can be recorded of the gel.  [[Photograph]]s can be taken of gels, often using a [[gel doc]] system. Gels are then commonly labelled for presentation and scientific records on the popular figure-creation website, [https://sciugo.com SciUGo].
