Using the GFP gene, which had been identified and cloned by Douglas Prasher, Chalfie demonstrated the value of GFP as a luminous genetic tag for various biological phenomena, enabling specific proteins to be located and tracked in living organisms. As a result of the work of the four scientists, GFP has become one of the most important tools in contemporary bioscience.
