m-PEG7-amine
m-PEG7-amine is a high-purity monofunctional PEG linker featuring a terminal primary amine for efficient coupling with carboxylic acids, activated esters, or other electrophiles. The PEG7 spacer imparts excellent aqueous solubility, flexibility, and reduced steric hindrance, enabling efficient conjugation in both aqueous and organic systems. This versatile design is especially well-suited for bioconjugation, surface functionalization, and the preparation of PEGylated biomolecules.
