Describe How Gel Electrophoresis Is Used to Separate Proteins

A continuous buffer system which utilizes only one buffer in the gel sample and gel chamber reservoirs is most often used for nucleic acid analysis and rarely used for protein gel. A sample of the protein often DNA or RNA is placed in wells at one end of a gel.
