| Description: | NH2-PEG6-Boc is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1]. NH2-PEG6-Boc is also a non-cleavable 6 unit PEG ADC linker used in the synthesis of antibody-drug conjugates (ADCs)[2]. | 
| Target: | PEGs Alkyl/ether Non-cleavable | 
| In Vitro: | 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[1]. ADCs are comprised of an antibody to which is attached an ADC cytotoxin through an ADC linker[2]. |
