| Description | Azido-PEG3-maleimide is a PEG-based PROTAC linker used primarily for the synthesis of PROTACs[1] and also functions as a cleavable 3-unit PEG ADC linker in the synthesis of antibody-drug conjugates (ADCs)[2]. |
| In vitro | PROTACs, comprising two ligands linked together—one targeting E3 ubiquitin ligase and the other the target protein—use the ubiquitin-proteasome system to selectively degrade target proteins[1]. ADCs consist of an antibody connected to a cytotoxin via an ADC linker[2]. |
