Abstract:
A major advance in the microscopic study of cells and tissues is the introduction of photoactivatable fluorescent proteins, which can specifically mark proteins of interest within a living cell. Fluorescent proteins are now available that allow a pool of molecules to be "turned on" by photoactivation. This unit discusses technical aspects for the general use of photoactivatable fluorescent proteins and introduces some specific applications in the concluding remarks.

Protein Dynamics in Living Cells
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...
