Collection: Fluorescent Labels

Fluorescent Labels — includes fluorescent dyes and labeling reagents such as fluorescein, cyanine (Cy5), and BODIPY derivatives equipped with reactive groups such as NHS ester, DBCO, or maleimide for covalent conjugation. This group serves as optical markers that enable tracking and visualization of biomolecules through fluorescence techniques.

Fluorescent Labels are used to label proteins, peptides, or nucleic acids for protein structure analysis, tracking of cellular localization, and detection in electrophoresis and fluorescence microscopy imaging. Proteomics and cell biology researchers use reactive groups such as NHS ester or DBCO for click conjugation reactions or for labeling free amines on target proteins, while sulfo derivatives improve solubility in aqueous solutions.

Example products in this collection: TCI A0306 3326-34-9 5-Aminofluorescein (isomer I), TCI B6232 146616-66-2 BDP FL NHS Ester (1mg*3), TCI U0186 449175-58-0 Sulfo-cyanine 5 Carboxylic Acid Potassium Salt, TCI B6253 2699028-49-2 2,5-BMeS-p-A-NHS, TCI U0172 146368-11-8 Sulfo-cyanine 5 Carboxylic Acid, TCI B6272 165599-63-3 BDP FL (1mg*3), TCI U0167 1394116-40-5 Sulfo-Cyanine 5 DBCO, TCI C1196 97744-77-9 4-Carboxymethyl-6,7-methylenedioxycoumarin.

Selection considers excitation-emission wavelengths, the type of reactive group (NHS ester, DBCO, maleimide) matching the target functional group, and solubility in aqueous or organic solvents. All products are genuine products of Tokyo Chemical Industry (TCI) Japan, with purity, packaging, and storage conditions listed on each item's page.

Other parallel categories under Fluorescent Probes, Fluorescent Labels, Fluorescent Stains, are often used together in a single laboratory workflow:

• Fluorescent Indicators and Fluorescent Probes
• Donors and Acceptors for FRET
• Fluorescence Quenchers

This collection is further divided into 1 more specific group:

• Protein Structural Analysis
