Branched PEG modifiers feature multiple PEG arms conjugated to a central core, creating multiple reactive sites for bioconjugation. These structures enhance payload shielding, minimize non-specific interactions, and provide controlled molecular spacing in biomolecular modifications. Offering flexible solutions for single- and multi-site conjugation, our multi-arm Maleimide, Amine, and Acid PEG linkers streamline conjugation analysis while improving stability and performance. With high-quality manufacturing and technical expertise, Vector Laboratories provides precision-engineered PEG modifiers that support reproducibility and reliability in protein, peptide, and drug applications.
