Fluorescent proteins: into the infrared

Allison Doerr

Fluorescent proteins have come along way since the discovery of GFP from the jellyfish Aequorea victoria in the early 1960s. Today, both natural and engineered fluorescent proteins come in a veritable rainbow of colors, largely thanks to pioneering work done in Roger Tsien's laboratory at the University of California at San Diego, work that was recently recognized with part of the 2008 Nobel Prize in Chemistry.
