Collection: Fluorescent Probes, Fluorescent Labels, Fluorescent Stains

Fluorescent Probes, Fluorescent Labels, Fluorescent Stains — covers fluorescent dyes, FRET donor-acceptor pairs, fluorescence quenchers, and reactive dye labels such as cyanine, fluorescein, and BODIPY derivatives used to provide optical signals to molecules or cells.

Materials in this category are used by molecular and cell biology researchers to label proteins, nucleic acids, or antibodies through reactive groups such as NHS ester or DBCO, as well as for nuclear staining of cells and FRET-based studies of molecular interactions. Donor-acceptor pairs and quenchers are used in the design of probes and fluorescence-based assays to detect conformational changes, intermolecular distances, or enzyme activity.

Example products in this collection: TCI A0306 3326-34-9 5-Aminofluorescein (isomer I), TCI B6123 2156642-70-3 BIP, TCI U0186 449175-58-0 Sulfo-cyanine 5 Carboxylic Acid Potassium Salt, TCI B6232 146616-66-2 BDP FL NHS Ester (1mg*3), TCI U0172 146368-11-8 Sulfo-cyanine 5 Carboxylic Acid, TCI B6236 23491-45-4 Bisbenzimide H 33258 (0.2mL*5) (1mg/mL in Water) [for Cell Staining], TCI U0167 1394116-40-5 Sulfo-Cyanine 5 DBCO, TCI B6253 2699028-49-2 2,5-BMeS-p-A-NHS.

Pay attention to excitation-emission wavelengths so they match the available detection instruments, the type of reactive group for conjugation (NHS ester, DBCO, maleimide), as well as the purity and packaging form of the dyes. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
