Abstract:
Whole-body imaging with fluorescent proteins is a powerful technology with many applications in small animals. Brighter, red-shifted proteins can make whole-body imaging more sensitive owing to reduced absorption by tissues and less scatter. A new protein called Katushka has been isolated. It is the brightest known protein with emission at wavelengths longer than 620 nm. This new protein offers the potential for noninvasive whole-body imaging of numerous cellular and molecular processes in live animals.

Fluorescent recovery after photobleaching (FRAP) is a fluorescent-protein-based detection technique used to quantify protein movement rates within the cell. This method exposes a small portion of the cell to an intense laser beam. The laser beam causes permanent photobleaching of the fluorophore-tagged proteins in the exposed region. As the bleached...
