Collection: Antibody Supplementary Products

Antibody Supplementary Products — contains reagents supporting antibody work, including chromogenic substrates, buffers, blockers, binding proteins (Protein A, G, L), streptavidin, and antibody modification and labeling materials for various detection formats. This collection complements the immunoassay workflow from conjugation to signal visualization.

Antibody Supplementary Products are used by immunology and molecular biology laboratories in the development of ELISA, western blot, and immunohistochemistry. Substrates such as 4-chloro-1-naphthol and tetrazolium derivatives act as colorimetric indicators, while fluorescein derivatives are used for labeling and fluorescence-based detection, and conjugated streptavidin supports the biotin-streptavidin detection system.

Examples of products in this collection: TCI A0257 22198-72-7 4-Aminoantipyrine Hydrochloride [for Biochemical Research], TCI C2291 604-44-4 4-Chloro-1-naphthol [for Biochemical Research], TCI A0306 3326-34-9 5-Aminofluorescein (isomer I), TCI C2477 76823-03-5 5-Carboxyfluorescein, TCI I0781 146-68-9 2-(4-Iodophenyl)-3-(4-nitrophenyl)-5-phenyltetrazolium Chloride [for Biochemical Research], TCI C2478 3301-79-9 6-Carboxyfluorescein, TCI T3885 Streptavidin R-PE Conjugate, TCI C2479 92557-80-7 5-Carboxyfluorescein N-Succinimidyl Ester.

Pay attention to the conjugation type (fluorescence, enzymatic, or biotin) and the compatibility of buffer and working pH, because the stability of the detection signal depends on how well the reagent matches the immunoassay system being used. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
