Electrophoresis

Electrophoresis is a scientific principle where particles suspended in a fluid which is subjected to a stable magnetic field will migrate in a single direction.
In many medical tests, this technique is used to separate proteins from other materials in a sample. It is particularly useful in the research of DNA and RNA and can show how proteins bind to those molecules. It is capable of separating proteins by size, density and purity.
