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.

CFDA-SE (solution)
0 ImagesCat. No.: HY-DY1009CAS No.: 150347-59-4CFDA-SE (solution) is a fluorescent dye that can penetrate the cell membrane. It can react with the free amine group in the cytoskeleton protein inside the cell, and finally form a protein complex with fluorescence. After entering the cell, CFDA-SE locates in the cell membrane, cytoplasm and nucleus, and the fluorescence staining is strongest in the nucleus. CFDA-SE dye can be uniformly inherited by the cells with cell division and proliferation, and its attenuation is proportional to the number of cell divisions. This phenomenon can be detected and analyzed by flow cytometry under the excitation light of 488 nm, and can be used to detect the proliferation of cells.

TOTO-3
0 ImagesCat. No.: HY-D0920CAS No.: 166196-17-4TOTO-3 is a cyanine nucleic acid intercalating fluorescent probe that binds to both RNA and DNA (Ex=642 nm, Em=660 nm). TOTO-3 cannot enter intact cells, but can penetrate cells with permeabilized plasma membranes, staining cytoplasmic RNA and nucleoli to distinguish intact cells from damaged ones. TOTO-3 is taken up by macrophages in an ultrasound-independent manner. TOTO-3 accumulates in tumor cells via ultrasound-mediated enhancement of plasma membrane permeability. TOTO-3 supports optical imaging for real-time assessment of plasma membrane integrity, nucleic acid detection, and monitoring of ultrasound-mediated intracellular delivery processes. TOTO-3 is applicable to studies related to rectal cancer.
