Cy5.5 PEG dye is a near infrared fluorescent dye with excitation/emission wavelength at 675 nm/694 nm. PEG linker between Cy5.5 and azide 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.
