Collection: Conjugation Chemistry/Click Chemistry

Conjugation Chemistry/Click Chemistry — covers reagents for conjugation chemistry and click chemistry—azides and terminal alkynes, tetrazines, trans-cyclooctene (TCO), biotin derivatives, PEG, fluorophores, carbohydrates, nucleosides, amino acids, as well as catalysts and supporting ligands for reactions. These materials facilitate selective bond formation between molecules in synthesis and biomolecule labeling.

Conjugation Chemistry/Click Chemistry reagents are used by bioorganic chemistry and chemical biology researchers for azide-alkyne cycloaddition reactions (CuAAC/SPAAC), tetrazine-TCO ligation, and labeling of proteins, carbohydrates, and nucleic acids with fluorophores or biotin. Applications include preparing tracking probes, PEG conjugates for solubility modification, and synthesis of compound libraries through fast and selective click reactions.

Pay attention to the type of reactive group (azide, alkyne, tetrazine, TCO), PEG spacer length, and solvent and target functional group compatibility so that the conjugation reaction runs selectively and efficiently. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
