Collection: Aldehyde Reactive Fluorophores and Labels [Conjugation Chemistry/Click Chemistry]

Aldehyde Reactive Fluorophores and Labels [Conjugation Chemistry/Click Chemistry] — includes simple hydrazide compounds through biotin-PEG-hydrazide derivatives and benzoxadiazole fluorophores bearing aldehyde-reactive groups, making them fluorescent or affinity labels for labeling carbonyl groups generated by periodate oxidation of glycoproteins and nucleic acids.

Hydrazide reagents and benzoxadiazole-derived fluorophores (NBD, DBD) in this category are used by bioconjugation researchers to bind aldehyde groups formed from periodate oxidation of sugar chains in glycoproteins, RNA, or reducing sugar ends, forming stable hydrazone bonds for HPLC detection or biotin-based affinity labeling. Biotin-hydrazide conjugates are commonly used in purification and detection using streptavidin systems.

Choose based on the length of the PEG linker, the fluorophore type (NBD or DBD) for a suitable detection wavelength, and whether biotin is conjugated directly or via a hexanoyl chain before reacting with the target aldehyde groups. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
