NH2-PEG4-CH2CH2COOH features a linear PEG4 spacer flanked by an amine handle and a terminal carboxylic acid, enabling dual conjugation versatility. This bifunctional linker facilitates site-specific coupling in bioconjugation workflows, offering enhanced solubility and stability under physiological conditions.
NH₂-PEG₄-CH₂CH₂COOH serves as a versatile bifunctional linker for conjugation workflows, combining the solubility and stability of a tetra(ethylene glycol) chain with orthogonal reactive handles. The terminal amine enables efficient coupling to carboxylated surfaces or biomolecules, while the β-carboxylic acid facilitates further derivatization via amide or ester formation. Its well-defined structure supports reliable purification and consistent performance in peptide, antibody-drug conjugate, and nanoparticle functionalization applications.
