Cy®3 is a bright, water-soluble, and pH insensitive orange-fluorescent dye that can be excited using the 532nm or 555nm laser line and visualised with TRITC (tetramethylrhodamine) filter sets. Cy3 conjugates give less background than TAMRA and most other commonly used fluorescent dyes.
The NHS ester (also known as succinimidyl esters) is the most popular amine-reactive variation of Cy®3 dye used for labelling proteins, antibodies, peptides, amine-modified oligonucleotides, and other amine-containing molecules with this dye.
This sulfonated dye is also known as sulfo-Cyanine 3 NHS ester. Cy® Dye is a trademark of GE Healthcare.
