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.

Rhodamine B-Dextran chloride (MW 500000)
0 ImagesCat. No.: HY-D3047IRhodamine B-Dextran (chloride) (MW 500000) is a Rhodamine B (HY-Y0016)-labeled dextran with a molecular weight of 500000. Rhodamine B-Dextran (chloride) (MW 500000) is a fluorescent dye used to track the diffusion of macromolecules in ex vivo human skin. Rhodamine B-Dextran (chloride) (MW 500000) is delivered to skin layers via the Nanopatch microneedle array, which physically disrupts the stratum corneum and dermal-epidermal junction barriers to deposit the dye directly into epidermal and dermal regions; fluorescence is detected via multiphoton microscopy, and fluorescence intensity is assumed to be roughly proportional to dye concentration.

DCM-KPV
0 ImagesCat. No.: HY-D3210CAS No.: 2098632-04-1DCM-KPV is a fluorescent probe targeting the human intestinal oligopeptide transporter PEPT1/SLC15A1 receptor (λex=480 nm, λem=620-670 nm). DCM-KPV specifically binds to PepT1 via its KPV domain and mediates receptor-targeted internalization, thus effectively accumulating in the cytoplasm and nucleus of cells overexpressing this receptor. DCM-KPV has the advantages of long emission wavelength, high emission efficiency, low photobleaching, and negligible cytotoxicity. DCM-KPV maintains stable fluorescence intensity under continuous illumination, exhibiting extremely high live cell compatibility. DCM-KPV can specifically accumulate at colonic inflammatory sites through the intestinal mucosa, enabling direct non-invasive visual differentiation between chronic and acute ulcerative colitis groups and the normal group.
