Nobel Laureate Roger Tsien Describes His Work
Tsien is renowned for revolutionizing the fields of cell biology and neurobiology by allowing scientists to peer inside living cells and watch the behavior of molecules in real time. He is well-known for developing colorful dyes, such as Fura-2, to track the movement of calcium within cells and has genetically modified molecules that make jellyfish and corals glow, creating fluorescent colors in a dazzling variety of hues. These multicolored fluorescent proteins are used by scientists to track where and when certain genes are expressed in cells or in whole organisms. More >
