After the gel electrophoresis, the gel is scanned with the [[excitation wavelength]] of each dye one after the other. This technique is used to see changes in protein abundance (for example, between a sample of a healthy person and a sample of a diseased person). [[Category:Electrophoresis]] {{biochem-stub}}
