Gel Diffusion

Technique The Gel Diffusion Technique is a method used to identify the amount and size of proteins in a given sample. It is based on the diffusion of the proteins through a gel and the time it takes for them to move through. By measuring the size of the protein, the diffusion rate and the distance the protein moves, it is possible to identify the composition of the sample. This technique is extremely useful in identifying the presence and concentration of proteins in a sample and is used in several fields such as biochemistry, virology and bacteriology.
