Gly-Gly-Gly-PEG4-DBCO is a four-unit polyethylene glycol (PEG) linker bearing a dibenzocyclooctyne (DBCO) reactive group used for bioconjugation and copper-free click chemistry (strain-promoted alkyne-azide cycloaddition, SPAAC) to couple azide-containing molecules. Typically used in antibody-drug conjugate linker synthesis and site-specific conjugation.
- Four-unit PEG spacer improves solubility and flexibility.
- DBCO group enables copper-free SPAAC click reactions with azides.
- Supplied in small-scale quantities suitable for research use.
- Characterized by molecular formula C35H46N6O9 and molecular weight 694.77.

Pomalidomide-PEG4-C-COOH (Cereblon Ligand -Linker Conjugate 1) is a synthesized E3 ligase ligand-linker conjugate that incorporates the Pomalidomide based cereblon ligand and 4-unit PEG linker used in PROTAC technology. 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.
- Synthesized E3 ligase ligand-linker conjugate
- Incorporates Pomalidomide based cereblon ligand
- Uses 4-unit PEG linker
- Used in PROTAC technology
