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.

RhoNox-4
0 ImagesRhoNox-4 is a ferroptosis inhibitor and a fluorescence activation indicator specific to Fe2+. RhoNox-4 selectively reacts with labile Fe2+ and oxidizes it to Fe3+, depleting labile Fe2+ involved in lipid peroxidation and inhibiting ferroptosis induced by ferroptosis inducers. RhoNox-4 is cell-permeable, accumulates in the endoplasmic reticulum and/or Golgi apparatus, can be used for live-cell imaging and high-throughput screening of subcellular iron status regulators, and is applicable to iron biology research.

Janelia Fluor® 549, SE
0 ImagesCat. No.: HY-130736CAS No.: 1811539-32-8Synonyms: JF549, SE; JF549, NHSJanelia Fluor? 549, SE (JF549, SE) is a cell-permeable fluorescent dye with an NHS ester (succinimidyl ester (SE)) reactive group. NHS esters react with primary amines and are commonly used to conjugate dyes to proteins, antibodies, amine-modified oligonucleotides, and other molecules. Janelia Fluor fluorescent dyes can be chemically conjugated to the specific HaloTag substrate (a chloroalkane ligand) to form a fluorescent ligand, rather than binding directly to the HaloTag protein itself. Janelia Fluor? 549, SE also acts as a ligand for self-labeling tags such as HaloTag and SNAP-tag, and can be used in live-cell imaging studies (Ex/Em = 549 nm/571 nm).
