Bis-propargyl-PEG8 is a PEG-based linker bearing two terminal propargyl (alkyne) groups designed for click-chemistry conjugation. It provides a flexible PEG8 spacer for use in PROTAC synthesis and other bioconjugation workflows, enabling copper-catalyzed azide-alkyne cycloaddition (CuAAC) between azide- and alkyne-functionalized partners.

• Contains two terminal alkyne groups for CuAAC click chemistry.
• Peg8 spacer improves solubility and provides flexible linker length.
• Suitable for synthesis of PROTACs and other bioconjugates.
• Available in laboratory-scale pack sizes for research use.
• Provided as a ready-to-use reagent for organic synthesis workflows.

Fmoc-amino-PEG3-CH2COOH is a PEG-based PROTAC linker. It is used in the synthesis of PROTACs, which are molecules containing two different ligands connected by a linker. One ligand is for an E3 ubiquitin ligase and the other is for the target protein. PROTACs utilize the intracellular ubiquitin-proteasome system to selectively degrade target proteins.

• PEG-based PROTAC linker
• Can be used in the synthesis of PROTACs
