An alkyne-activated, water-soluble Cy5.5 dye.
The NIR-fluorescent Cy5.5 azide can be reacted with terminal alkynes via a copper-catalysed click reaction (CuAAC). Cy5.5 is a water-soluble, pH-insensitive, bright fluorescent probe that can be used in place of Alexa Fluor® 680, DyLight® 680, or IRDye™ 680 and other dyes excitable at a wavelength at around 680 nm.
This sulfonated dye is also known as sulfo-Cyanine 5.5 Alkyne. Cy® Dye is a trademark of GE Healthcare.
