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.

Dexamethasone fluorescein
0 ImagesArt. -Nr.: HY-D3485CAS. Nr.: 216854-76-1Dexamethasone fluorescein is a fluorescently labeled steroid conjugate that binds to glucocorticoid receptors. Dexamethasone fluorescein binds to glucocorticoid receptors. Dexamethasone fluorescein serves as a marker for evaluating the delivery of drugs via subconjunctival injection and intratympanic administration. Sustained transscleral diffusion is achieved when Dexamethasone fluorescein is delivered via fibrin sealant. Dexamethasone fluorescein can be used to investigate the binding and localization of glucocorticoid receptors.

Xylenol blue
0 ImagesXylenol Blue is a sulfonephthalein dye. It exhibits observable color changes in response to variations in pH. Xylenol Blue undergoes two distinct color transitions across two specific pH ranges: an acidic range and an alkaline range. In a neutral solution, Xylenol Blue appears yellow (at pH 8); in a strongly acidic medium, its color shifts to red (at pH 2.8); and in an alkaline medium, the yellow hue transitions to blue (at pH 9.6).
