Fluorescent Indicators and Fluorescent Probes

Fluorescent Indicators and Fluorescent Probes — a collection of fluorescent molecules such as anilinonaphthalenesulfonate (ANS) derivatives in various salt forms, methylated rhodamine esters, and quinoline compounds such as TSQ that emit fluorescence when bound to a hydrophobic environment or specific ions. These fluorescent properties make them tools for tracking changes in protein conformation and molecular microenvironments.

Fluorescent probes in this category are used by biochemistry and cell biology researchers to monitor protein conformational changes through ANS binding to hydrophobic cavities, and to track the potential of mitochondrial membranes using methylated rhodamine esters. TSQ is commonly used in studies of metal ion binding, such as zinc, in fluorescence-based systems.

Example products in this collection: TCI T4347 109628-27-5 TSQ, TCI B6654 627810-06-4 BMVC, TCI T3608 115532-50-8 Tetramethylrhodamine Methyl Ester Perchlorate, TCI B6675 850559-51-2 BMVC2, TCI A5353 18108-68-4 ANS-Mg (=Magnesium(II) 8-Anilino-1-naphthalenesulfonate) [Hydrophobic fluorescent probe], TCI C2806 1611477-45-2 Cesium Green, TCI A5352 1445-19-8 ANS-Na (=Sodium 8-Anilino-1-naphthalenesulfonate) [Hydrophobic fluorescent probe], TCI C2859 79955-27-4 5-Carboxyfluorescein Diacetate.

Choose the salt form (sodium, ammonium, or magnesium) according to the solubility requirements of the test medium, and pay attention to the specific excitation/emission wavelengths of each probe so they match the available detection instrument. All products are original Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
