Three scientists will share this year's Nobel Prize for Chemistry in recognition of their contribution to the discovery and development of the green fluorescent protein GFP.
By using DNA technology, researchers can now connect GFP to other proteins that were previously invisible, or to various cells, the Nobel Foundation said. The glowing marker allows them to watch the movements, positions and interactions of whatever carries the glowing tag.
The Nobel Foundation said GFP can help with researching nerve cell damage during Alzheimer's disease or insulin-producing beta cells created in the pancreas of a growing embryo. In one spectacular experiment, researchers succeeded in tagging different nerve cells with "a kaleidoscope of colors" in the brain of a mouse, the foundation said.
