Fluorescence/Luminescence Spectroscopy Reagents

Fluorescence/Luminescence Spectroscopy Reagents — includes dye compounds and fluorescent or luminescent probes that emit light at characteristic wavelengths after excitation, used as spectroscopic markers. This group brings together probes based on fluorescein, coumarin, cyanine, and potential membrane marker compounds.

Fluorescence/Luminescence Spectroscopy Reagents are used by biochemistry and cell biology researchers for cell imaging, fluorometric determination of calcium ion levels with calcein, and monitoring of mitochondrial membrane potential using JC-1. Coumarin dyes and cyanine derivatives are also used as laser dyes and labels in various fluorescence spectroscopy assays in the laboratory.

Example products in this collection: TCI A0306 3326-34-9 5-Aminofluorescein (isomer I), TCI C0003 Calcein Sodium Salt (mixture of isomers) [for Fluorometric Determination of Ca], TCI I0840 540-38-5 4-Iodophenol [for Biochemical Research], TCI C0004 154071-48-4 Calcein (mixture of isomers) [for Fluorometric Determination of Ca], TCI U0186 449175-58-0 Sulfo-cyanine 5 Carboxylic Acid Potassium Salt, TCI C2267 41267-76-9 Coumarin 102, TCI T4300 3520-43-2 JC-1, TCI C2268 55804-66-5 Coumarin 314.

Pay attention to the excitation and emission wavelengths that match your instrument, solubility in aqueous or organic solvents, and the isomer or salt forms available for each product. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
