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.

JF629-HTL
0 ImagesCat. No.: HY-D3445CAS No.: 3029700-80-6JF629-HTL is a far-red fluorogenic HaloTag ligand. Binding of JF629-HTL to HaloTag protein alters the local environment of the dye, promoting the transition of rhodamine from a non-fluorescent state to a fluorescent state, thereby generating a fluorescence enhancement signal. In the light-controlled psHaloTag system, JF629-HTL shows a 6.7-fold fluorescence enhancement after irradiation at 450 nm. JF629-HTL serves as a research tool for far-red fluorescence imaging and the development of chemogenetic biosensors.
