4-ArmPEG succinimidyl glutarate (4-ArmPEG-SG) is a  four-arm PEG derivative, where each arm is terminated with a succinimidyl glutarate functional group (SG). The succinimidyl group is reactive towards primary amines, forming stable amide bonds. The glutarate moiety provides a spacer arm, enabling the attachment of biomolecules or other ligands.

4-ArmPEG-SG is commonly used for crosslinking proteins, peptides, nucleic acids, or other molecules containing primary amine groups. It allows for the creation of multifunctional biomaterials, hydrogels, or nanoparticles with tailored properties for various biomedical applications, including drug delivery, tissue engineering, and diagnostics.
