Medchemexpress LLC M-PEG12-NHS ester | 2207596-93-6 | ≥98.0% | C30H55NO16 | 500 MG
m-PEG12-NHS ester is a PEG-based PROTAC linker designed for the synthesis of PROTACs. PROTACs utilize the intracellular ubiquitin-proteasome system to selectively degrade target proteins by connecting a ligand for an E3 ubiquitin ligase and a ligand for the target protein via a linker.
- PEG-based PROTAC linker
- Used in the synthesis of PROTACs
- Exploits ubiquitin-proteasome system to degrade target proteins
