Medchemexpress LLC Bromo-PEG6-Boc | 1393330-41-0 | 97.0% | C19H37BrO8 | 250 MG
Bromo-PEG6-Boc is a PEG-based PROTAC linker used in the synthesis of PROTACs.
- 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.
