Thiofluor 623

Catalog No.: A44810
Fluorescent Probe
Thiofluor 623 is a fluorescent probe designed for the selective sensing and bioimaging of thiols. It operates on a turn-on mechanism, becoming highly fluorescent upon reaction with thiols, which cleave the probe to release a red-emissive donor-acceptor fluorophore (Ex=563 nm, Em=623 nm). Notably, Thiofluor 623 exhibits excellent selectivity against interference from nitrogen and oxygen nucleophiles, making it an ideal tool for biological applications that require sensitive detection of thiol compounds.
