WebAbstract— Several bioluminescent coelenterates use a secondary fluorescent protein, the green fluorescent protein (GFP), in an energy transfer reaction to produce green light. The most studied of these proteins have been the GFPs from the jellyfish Aequorea victoria and the sea pansy Renilla reniformis. Webprotein absorbs the blue light emitted by aequorin (l max = 470 nm) and ﬂuor-esces green (l max = 509 nm). 7,8 Hence it was named green ﬂuorescent protein (GFP),9 eqn (1). It was easier to isolate aequorin than GFP, therefore Shimomuraconcentrated most of his research eﬀort on studying aequorin6,10,11 and he thinks that his best

Douglas C. Prasher (born August 1951) is an American molecular biologist. He is known for his work to clone and sequence the genes for the photoprotein aequorin and green fluorescent protein (GFP) and for his proposal to use GFP as a tracer molecule. He communicated his pioneering work to Martin Chalfie and Roger Y. Tsien, but by 1991 was himself unable to obtain further research funding, and left academia. Eventually, he had to abandon science.
