m-PEG5-Br is a PEG-based PROTAC linker. It is for research use only and not for sale to patients. This linker can be used in the synthesis of PROTACs, which consist of 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.
- Used in the synthesis of PROTACs
- Utilizes the intracellular ubiquitin-proteasome system
- Selectively degrades target proteins

m-PEG3-Aminooxy is a PEG-based PROTAC linker designed for the synthesis of PROTACs. PROTACs are compounds that contain two different ligands connected by a linker; one ligand targets an E3 ubiquitin ligase and the other targets a specific protein, enabling the degradation of target proteins through the intracellular ubiquitin-proteasome system.
- PEG-based linker
- Used in the synthesis of PROTACs
- Exploits the intracellular ubiquitin-proteasome system
- Selectively degrades target proteins
- For research use only
