Medchemexpress LLC m-PEG24-NHS ester | 2395839-96-8 | 99.7% | 50 MG
m-PEG24-NHS ester is a PEG-based PROTAC linker used in the synthesis of PROTACs. PROTACs are designed with two different ligands connected by a linker, where one ligand binds to an E3 ubiquitin ligase and the other to a target protein. They harness the intracellular ubiquitin-proteasome system to selectively degrade target proteins. This product is intended for research use only.
- PEG-based PROTAC linker
- Used for PROTAC synthesis
- Appearance: White to off-white solid
- Purity (HPLC): 99.7%
