Abstract:
Recordings from single molecule experiments can be aggregated to determine average kinetic properties of the system under observation. The kinetics after a synchronized reaction step can be interpreted using all of the standard tools developed for ensemble perturbation experiments. The kinetics leading up to a synchronized event, determined by the lifetimes of the preceding states; however, are not as obvious if the reaction has reversible steps or branches. Here we describe a general procedure for dealing with these situations.

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...
