Biotin and derivatives
Medchemexpress LLC Biotin-PEG8-NHS ester | 2143968-03-8 | 99.89% | C33H56N4O14S | 50 MG
Biotin-PEG8-NHS ester is a PEG-based PROTAC linker utilized in the synthesis of PROTACs. PROTACs consist of two distinct ligands connected by a linker, where one ligand targets an E3 ubiquitin ligase and the other targets a specific protein. These molecules leverage the intracellular ubiquitin-proteasome system to selectively degrade target proteins. The product is intended for research use only.
- Utilized in the synthesis of PROTACs
- Exploits the intracellular ubiquitin-proteasome system
- Selectively degrades target proteins
- Intended for research use only
