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.

PE-Cy5.5
0 ImagesCat. No.: HY-D3275PE-Cy5.5 is a far-red emitting tandem dye designed based on the principle of fluorescence resonance energy transfer (FRET), and is widely used in multicolor flow cytometry. PE-Cy5.5 consists of phycoerythrin (PE) as the energy donor and the cyanine dye Cy5.5 as the energy acceptor. Upon excitation by blue or green laser light, PE absorbs energy and transfers it to Cy5.5 via FRET, ultimately resulting in Cy5.5 emitting characteristic far-red fluorescence (Ex/Em = 450-500 nm/698 nm).
