Collection: Antibody Modification

Antibody Modification — includes fluorescent dyes, lanthanide-chelate compounds, and succinimidyl esters such as coumarin derivatives used as reactive labels for covalent modification of proteins and antibodies.

Compounds in this category are used by immunochemistry researchers and diagnostic reagent developers to label antibodies or proteins through covalent bonds to amine groups, producing fluorescent conjugates used in detection techniques such as ELISA, immunofluorescence, or time-resolved fluorescence using lanthanide complexes. Label selection is adjusted to the excitation-emission wavelengths required by the detection instrument.

Example products in this collection: TCI A0306 3326-34-9 5-Aminofluorescein (isomer I), TCI C2477 76823-03-5 5-Carboxyfluorescein, TCI A2083 601494-52-4 ATBTA-Eu3+, TCI C2478 3301-79-9 6-Carboxyfluorescein, TCI A0864 51649-83-3 6-Aminofluorescein (isomer II), TCI C2479 92557-80-7 5-Carboxyfluorescein N-Succinimidyl Ester, TCI S0891 100900-07-0 Sodium 5-(2-Aminoethylamino)-1-naphthalenesulfonate, TCI C3710 3348-03-6 6-Carboxyfluorescein Diacetate.

Pay attention to the type of reactive group (NHS ester, maleimide) suitable for the conjugation target on the antibody, as well as the spectral characteristics (excitation/emission) of the selected fluorescent or lanthanide label. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
