Abstract:
The synthesis and utility of attachable cyclopenta[b]naphthalene solvatochromic fluorophores related to Prodan are described. Two fluorophores were selected for functionalization and bioconjugation studies. The skeletons were chemically modified to include reactive functional groups and showed minimal alteration of the optical properties when compared to the parent dyes. The functionalized fluorophores were covalently attached to the carboxyl group of a fatty acid, and azido- and thiol-containing amino acids, demonstrating their potential for labeling biomolecules.

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...
