WebSo how does gel electrophoresis work? It is based on the principle that nucleic acids, like DNA and RNA, are negatively charged. This means that if you put nucleic acids in an electric field, they will migrate away from the negative end of the field and toward the positive end. The nucleic acids are placed inside the gel for two main reasons. WebCapillary gel electrophoresis (CGE) is a CE version of slab-gel electrophoresis and is used for size-based separation of biological macromolecules such as oligonucleotides, DNA …
