Abstract:
Thiols are important units in amino acids such as cysteine and peptides like glutathione. Development of chemical sensors capable of precise detection of thiols is important in cancer diagnosis and therapy. We have developed novel two-photon fluorescent turn-on probes for selective detection of thiols. The probes displayed excellent sensitivity and low detection limits. The dual-purpose probes have been demonstrated to be suitable for simultaneous imaging and proteome profiling in live cells and tumor tissues. The unique turn-on design endows the probes with excellent selectivity toward thiols in vitro and in situ, and can be further developed to support a thiol-quantification assay.

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...
