gel electrophoresisELECTROPHORESIS in a gel matrix, commonly agarose or polyacrylamide. This technique allows molecules to be separated on the basis of charge-to-size ratio, using the gel as a support and a sieving material. For example, sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDSPAGE) can be used to separate PROTEINS, and agarose or polyacrylamide gel electrophoresis (PAGE) to separate NUCLEIC ACIDS.
