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.

Cy3 labled Eteplirsen sodium
0 ImagesCat. No.: HY-108753ECy3 labled Eteplirsen sodium is a Cy3 labled Eteplirsen (AVI 4658) sodium (HY-108753A). Eteplirsen (AVI 4658) sodium is a phosphorylated diamine morpholino oligonucleotide that targets exon 51 of the human Duchenne muscular dystrophy (DMD) gene. Eteplirsen sodium induces exon 51 skipping, causing it to be skipped during splicing, thereby restoring the translation reading frame and producing a shortened functional dystrophin. Eteplirsen sodium can be used in research on Duchenne muscular dystrophy.
