Abstract:
Photoconvertible fluorescent proteins (pcFPs) enable differential coloring of a single organelle. Several pcFP-based probes have been targeted to the endoplasmic reticulum (ER) and can serve as useful tools to study ER dynamics and interactions with other organelles. Here, we describe the procedure to conduct live-cell imaging experiments using ER-targeted pcFP-based probes. Potential problems that might occur during the experiments, their solutions, and several ways to improve the experiments are discussed.

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...
