Xanthene Dyes — gathers dye compounds based on the xanthene framework, such as rhodamine and fluorescein and their derivatives, which are known to have strong fluorescence and absorption-emission spectra in the visible wavelength range. Their main role is as fluorescent dyes and optical probes in various molecular detection techniques.
Xanthene Dyes are commonly used as fluorescent dyes or labelling agents in fluorescence microscopy, flow cytometry, and real-time PCR-based detection, including as reporter groups on oligonucleotide probes. Molecular biology researchers and analytical chemists use derivatives such as rhodamine and fluorescein for molecule tracking, cell staining, and as indicators in complexometric titrations.

Pay attention to the functional group form (methyl ester, carboxylic acid, salt form) as well as purity and positional isomers (5- vs 6-), as these affect the excitation-emission spectrum and conjugation compatibility. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
