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.

Mito-RhFe
0 ImagesCat. No.: HY-D3128CAS No.: 2348351-60-8Mito-RhFe is a Fluorescent probe for mitochondrial labile Fe³⁺ monitoring via imaging and flow cytometry. This probe is a rhodamine-based construct with a spirolactam fluorescence signaling group and an N2-hydroxyethyldiethylenetriamine chelator; its delocalized positive charge enables mitochondria-targeting ability in live cells, and it exhibits fine cell membrane permeability. In its native state, it exists in the non-fluorescent spirolactam form, but upon binding to Fe³⁺, it undergoes a ring-opening conversion to the fluorescent rhodamine form, triggering a turn-on fluorescent response; this process is reversible, as the addition of the metal chelator TPEN removes Fe³⁺ and converts the probe back to its non-fluorescent spirolactam form, and re-addition of Fe³⁺ restores fluorescence. The probe shows high selectivity for Fe³⁺ over most other metal cations present in living systems, with a ~90-fold fluorescence enhancement upon binding to 20 equiv of Fe³⁺. Mito-RhFe has excitation/emission wavelengths of Ex/Em = 540/578 nm, with an ~8 nm bathochromic shift in emission upon Fe³⁺ binding, and it can also be excited at 543 nm for confocal imaging with emission detected at 570-620 nm[1].
