PEG3-O-CH2COOH features a short polyethylene glycol chain terminated by a reactive carboxylic acid group, enabling efficient conjugation in bioconjugation workflows. This water-soluble linker combines stability with ease of coupling, facilitating site-specific modifications in peptide and protein engineering applications.
PEG3-O-CH2COOH serves as a versatile bifunctional linker for conjugation workflows, combining the solubility and biocompatibility of triethylene glycol with a terminal carboxylic acid. It enables efficient amide coupling reactions under standard conditions, facilitating site-specific attachment to amines in peptides, proteins, and biomolecules. The PEG3 spacer provides enhanced flexibility and reduced steric hindrance, while the stable, bench-ready structure supports straightforward purification and reproducible functionalization in synthetic and bioconjugation applications.
