Chromatography

Chromatography is a very powerful method that can be used for the purification and separation of molecules in the laboratory. For example, without chromatography, and the work of a Banting, Best and a biochemist called Collip (who perfected the purification), we would have no treatment for type I diabetes, that is, insulin would not have been discovered. Without chromatography we wouldn’t be able to sequence DNA, perform PCR, and many drugs and biological mechanisms would not have been discovered.
