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.

LCP
0 ImagesCat. No.: HY-D3251LCP is a polar-responsive fluorescent probe for the cellular microenvironment. LCP responds to polarity changes in the cellular microenvironment via fluorescence resonance energy transfer, emitting blue fluorescence in low-polarity environments (Ex/Em = 420 nm/550 nm) and red fluorescence (Ex/Em = 500 nm/662 nm) in high-polarity environments. LCP enables dual-color visualization of dynamic changes in lysosomes and cytoplasmic membranes during cell apoptosis, and monitors cell viability through localization and emission color changes. LCP can be used in cancer research.
