Agarose Gel Electrophoresis: As described earlier, agarose gel electrophoresis is used to separate DNA fragments based on their size. It is commonly used for DNA analysis, such as genotyping, DNA sequencing, and restriction enzyme digestion. The agarose gel electrophoresis equipment carries the electrophoresis chamber, gel caster, gel comb, electrodes, and clamps (labeled on the above figure). The gel electrophoresis chamber is made up of high-quality acrylic. Learn how to separate DNA, RNA, or proteins based on their size and charge using agarose gel electrophoresis. Find out the steps involved, the staining and visualization methods, and the applications in molecular biology, forensics, and medicine. Agarose gel electrophoresis is a method of gel electrophoresis used in biochemistry, molecular biology, genetics, and clinical chemistry to separate a mixed population of macromolecules such as DNA , RNA or proteins in a matrix of agarose.
