1 Japanese and 2 American scientists to obtain this year’s Nobel Prize in Chemistry Wednesday to take some of the ability to light-emitting jellyfish green and into a ubiquitous tool of molecular biology to watch the dance of living cells and proteins.
Xiu Scott, a Professor Emeritus of the Marine Biological Laboratory in Woods Hole, Massachusetts, and Boston University School of Medicine, Martin Chalfie, Columbia University and Roger yuan of the University of California, San Diego, will share 1,400,000 U.S. dollars prize from Sweden Royal Academy of Sciences.
Green fluorescent protein, or GFP short-term, it was in 1962 in Victoria medusa jellyfish, which drift in ocean currents from the west coast of North America.

Dr. Scott was able to identify the protein and showed that light-emitting bright green under ultraviolet light.

Dr. Chalfie showed that the protein can be used as a biological marker to identify the inserted gene of the protein produced by an organism’s DNA.

In early experiments, he inserted the protein is divided into six cells in a transparent roundworm. When placed under ultraviolet light, green light-emitting cells, they are exposed.

Dr. Qian was able to light-emitting-color other than green, so that biologists to track different cellular processes at the same time.

Biologists are now frequently used green fluorescent protein to track the growth and the fate of specific cells such as nerve cell damage in Alzheimer’s disease.

The technology can track a specific protein in the cells. In one experiment, the mouse brain into a kaleidoscope of different colors marked nerve cells with different fluorescent proteins.
