Amino-PEG10-acid（Cat No.:I045938）is a heterobifunctional polyethylene glycol linker bearing a terminal primary amine and a terminal carboxylic acid separated by a ten-unit PEG chain. The amine reacts efficiently with NHS esters, activated carboxyls (EDC/NHS), aldehydes via reductive amination, isocyanates, and epoxides to form stable linkages. The acid couples with primary amines to yield robust amide bonds, enabling orthogonal, sequential conjugations. PEG10 imparts high aqueous solubility, flexibility, and low nonspecific adsorption while providing controlled nanoscale spacing. Ideal for protein/peptide conjugation, nanoparticle and surface modification, hydrogel crosslinking, and modular drug–linker assembly.
