Homobifunctional PEGs

Homobifunctional PEGs are a class of polyethylene glycol derivatives featuring identical reactive groups at both ends, such as Acid-PEG-Acid, Amine-PEG-Amine, Mal-PEG-Mal, and Propargyl -PEG-Propargyl . These symmetric linkers enable efficient and controllable cross-linking of biomolecules or materials, making them essential for constructing stable molecular networks—including hydrogels, protein assemblies, and diagnostic sensor arrays.  Their reliability and structural simplicity establish Homobifunctional PEGs as fundamental tools in bioconjugation, biomaterial engineering, and assay development.
