Dioxoisoindolin-O-PEG-OH (MW 2000) is a polyethylene glycol (PEG)-based linker utilized for the synthesis of PROTACs (proteolysis targeting chimeras)[1].
m-PEG-OH (MW 2000) is a PEG-based linker for PROTACs which joins two essential ligands, crucial for forming PROTAC molecules. This linker enables selective protein degradation by leveraging the ubiquitin-proteasome system within cells.
Tr-PEG6-OH is a 6-unit polyethylene glycol (PEG) linker, which is non-cleavable and extensively employed in the synthesis of antibody-drug conjugates (ADCs).
Tr-PEG2-OH is a PEG-based PROTAC linker utilized in PROTAC synthesis[1]. It also serves as a non-cleavable 2-unit PEG ADC linker for the synthesis of antibody-drug conjugates (ADCs)[2].
