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.

Alizarin Red S Indicator (4.3-6.3), IND
0 ImagesCat. No.: HY-W110927CAS No.: 130-22-3Alizarin red S indicator (C.I. 58005) is a reductively active (quinone-based) anthraquinone dye that forms complexes with metal ions (such as zirconium, calcium) or boric acid to label calcium deposition and perform electrochemical sensing functions. Alizarin Red S undergoes reversible redox reactions (for electrochemical detection) and irreversible chelation (for bone staining). Alizarin Red S is mainly used in bone metabolism research (labeling mineralized tissue), sugar detection (boric acid-sugar competition system) and metal ion sensing (such as zirconium ion detection)， and can be used in osteoporosis and metabolic disease research.
