Webylaminopropyl) carbodiimide hydrochloride (EDC) reacts with carboxylated NPs in the presence of sulfo- N-hydroxylfo-succinimide (sulfo-NHS) to form amine-reactive sulfo-NHS esters. Subsequent addition of antibodies results in coupling between the NPs and primary amines on the antibody via a stable amide bond. WebJul 5, 2011 · Although carbodiimides and succinimides are broadly employed for the formation of amide bonds (i.e., in amino acid coupling), their use in the coupling of peptides to water-soluble carboxylic-terminated colloidal gold nanoparticles remains challenging. In this article, we present an optimization study for the successful coupling of the …
