Cy5.5 PEG Hydrazide, Cy5.5-PEG-NHNH2:
Cy5.5 PEG Hydrazide is one of Nanocs" reactive near infrared fluorescent dyes with a terminal hydrazide group (-NHNH2). Hydrazide is a carbonyl reactive functional group that can react with aldehyde or ketone group to form a stable hydrazone bond. Reaction of hydrazide and carbonyl group allows conjugation of Cy5.5 dye to polysaccharides, glycosylated proteins, antibodies and enzymes. Cy5.5 PEG dye is a bright near infrared fluorescent dye with excitation/emission wavelength at 675 nm/694 nm. PEG linker between Cy5.5 and hydrazide group offers better water solubility, reduced steric hindrance and enhanced stability. Compared to other fluorescent dyes, Nanocs’ reactive fluorescent PEG dyes are brighter, more stable and easier to use. All our reactive fluorescent PEG dyes can be used directly in aqueous buffer without need adding any organic solvents.
