 | Hazard Information | Back Directory |  | [Description] 
 Fluorescein-PEG4-azide is a green emitting fluorescent dye derivitative with excitation/emmission maximum 494/517 nm containing an azide group, which enables Click Chemistry. The hydophilic PEG spacer increases solubility in aqueous media and reduces steric hindrance during binding.
 |  | [Uses] 
 Fluorescein-thiourea-PEG4-azide is a PEG-based PROTAC linker can be used in the synthesis of PROTACs. Fluorescein-thiourea-PEG4-azide is a click chemistry reagent, it contains an Azide group and can undergo copper-catalyzed azide-alkyne cycloaddition reaction (CuAAc) with molecules containing Alkyne groups. It can also undergo strain-promoted alkyne-azide cycloaddition (SPAAC) reactions with molecules containing DBCO or BCN groups.
