Agarose Gel Electrophoresis

A technique in which large biomolecules are separated on a highly purified agarose gel by electrophoresis. AGE is used in clinical chemistry to separate mixtures of proteins by charge and size, and in molecular biology to separate mixtures of nucleic acid (DNA and RNA) fragments by sieving (movement of molecules through the gel’s pores) and size, where shorter molecules move faster and migrate farther than longer ones because shorter molecules migrate more easily through gel pores.
