The most studied of these proteins have been the GFPs from the jellyfish Aequorea victoria and the sea pansy Renilla reniformis.

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. Chalfie and Tsien … WebGreen-fluorescent protein (GFP), one of the hottest new biological tools, is responsible for the stunning bioluminescence of the Pacific Northwest Jellyfish, Aequorea victoria. While in its native host, GFP emits a green colored light when it accepts blue light from a calcium activated photoprotein.

If GFP is exposed to light, it emits a green fluorescent signal. This property has had an enormous impact on cell biology by enabling the imaging of almost any protein, in transcription studies by working as a reporter gene, and in biochemical applications. 2. Origin of GFP

WebPurified GFP, a protein of 238 amino acids (3), absorbs blue light (maximally at 395 nm with a minor peak at 470 nm) and emits green light (peak emission at 509 nm with a shoulder at 540 nm) (2, 4).
