Cy5.5-PEG-SH (MW 10000)

Cy5.5-PEG-SH (MW 10000) is a fluorescent labeling reagent that combines Cy5.5 fluorescent dye, polyethylene glycol (PEG) and sulfhydryl (SH) derivatives, and is suitable for molecular coupling. SH is highly reactive and can react with a variety of functional groups (such as maleimide) to form stable thioether bonds.
