Cy3-PEG-SH (MW 10000)

Cy3-PEG-SH (MW 10000) (Cy3-PEG-Thiol) is a near infrared fluorescent labeling reagent that combines Cy3 fluorescent dye, polyethylene glycol (PEG) and sulfhydryl (SH) polyethylene glycol derivatives, and is suitable for molecular coupling. Cy3-PEG-SH (MW 10000) is absorbed at 550nm and has high solubility and end-group substitution rate[1].
