Azide-PEG-amine (MW 5000)

• CAT Number: I045922
• Molecular Weight: 5000(Average)
• Purity: ≥95%

Azide-PEG-amine (MW 5000) is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1]. Azide-PEG-amine (MW 5000) 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. Strain-promoted alkyne-azide cycloaddition (SPAAC) can also occur with molecules containing DBCO or BCN groups.
PROTACs contain two different ligands connected by a linker; one is a ligand for an E3 ubiquitin ligase and the other is for the target protein. PROTACs exploit the intracellular ubiquitin-proteasome system to selectively degrade target proteins[1].
