Collection: Azides [Conjugation Chemistry/Click Chemistry]

Azides [Conjugation Chemistry/Click Chemistry] — contains compounds bearing reactive azide groups, including biotin-labeled PEG derivatives and acetylated sugars bearing azide, which function as reaction partners for azide-alkyne cycloaddition. This category also contains tetrazine molecules used in pairs with azides in bioorthogonal conjugation schemes.

Azides are used by conjugation chemistry researchers for click chemistry reactions based on cycloaddition with alkynes or cyclooctynes in protein labeling, creation of bioorthogonal conjugates, and surface modification of biomolecules. Biotin-PEG-Azide derivatives are commonly used to link labeled biomolecules to streptavidin-based detection systems, while azido sugars are used in metabolic labeling studies of glycans.

Pay attention to the length of the PEG linker (spacer), the type of pairing functional group at the other end of the molecule (biotin, bromo, or tetrazine), as well as the small pack formats that make handling easier at conjugation reaction scale. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
