Cy3-PEG-Thiol

Cy3-PEG-Thiol (Cy3-PEG-SH) 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-Thiol is absorbed at 550nm and has high solubility and end-group substitution rate[1].
