Cyanine3B azide

Catalog No.: A45529
Fluorescent Dye
Cyanine3B azide is a fluorescent dye designed for click chemistry applications, specifically for conjugation with terminal alkynes via copper-catalyzed reactions or with strained cyclooctynes through copper-free methods. This yellow-emitting cyanine dye exhibits enhanced fluorescence quantum yield and photostability, attributed to its fixed conformation, making it one of the brightest dyes in its class. Due to its non-sulfonated nature, an organic co-solvent such as DMF or DMSO is recommended for optimal labeling efficiency in aqueous environments.
