Fluorescent Dye

Fluorescence is a phenomenon of photoluminescence in luminescence. When an atom is irradiated by light, some electrons around the nucleus jump from their original orbitals to higher energy orbitals under the influence of light energy, i.e., from the ground state to the first or second excited single-line state, etc. Due to the instability of the first or second excited singlet state, the electron returns from the excited singlet state to the ground state accompanied by released energy, resulting in fluorescence.

Fluorescent dyes can be covalently bound or physically adsorbed in the structure of the substance. The fluorescence properties allow for the characterization, localization and quantitative analysis of the labeled object. Fluorescent dyes have shown great potential for the detection of proteins, nucleic acids, cells, and immunoassays, attributed to the advantages in non-radioactive contamination, simple experimental operation and easy observation.

Fluorescent dyes have penetrated many fields such as pharmacology, physiology, environmental science, and information science, as well as functional studies of proteins and drug screening.

    CycLuc1 methyl ester
    CycLuc1 methyl ester (Example 1) is a selective CES1 substrate and indirect bioluminescent inducer. CycLuc1 methyl ester undergoes catalytic hydrolysis via CES1-mediated ester bond cleavage to form a carboxyl product. The carboxyl product of CycLuc1 methyl ester undergoes an oxidation reaction with luciferase to generate a detectable bioluminescent signal. CycLuc1 methyl ester enables quantitative detection of CES1 activity.
