m-PEG8-amine
m-PEG8-amine is a high-purity monofunctional PEG linker featuring a terminal primary amine group for efficient conjugation with activated esters, aldehydes, and other electrophiles. The PEG8 spacer specifically enhances solubility in aqueous and organic solvents, improves molecular flexibility, and reduces steric hindrance in bioconjugation and surface modification processes.
