N-Hydroxysuccinimide
Based on 8 publication(s) in Google Scholar
N-Hydroxysuccinimide (HOSu; 1-Hydroxy-2,5-pyrrolidinedione) is a covalent crosslinker commonly used in bioconjugation technology with a primary amine group. N-Hydroxysuccinimide reacts with amino groups (-NH2) to form a stable amide bond, which can modify amino-containing biomolecules. N-Hydroxysuccinimide can be used, for example, for protein labeling with fluorescent dyes and enzymes, surface activation of chromatography supports, microbeads, nanoparticles and microarray slides, and chemical synthesis of peptides. N-Hydroxysuccinimide has a wide range of applications in biomaterial synthesis (such as collagen, chitosan crosslinking), drug delivery systems (such as hydrogel preparation) and tissue engineering.

In the cross-linking experiment of collagen solution, N-Hydroxysuccinimide-activated adipic acid was used to confirm the formation of intermolecular cross-linking by SDS-PAGE. Fluorescence spectroscopy showed that the polarity of the collagen microenvironment increased after cross-linking. Atomic force microscopy observed that collagen molecules randomly aggregated, which can improve the self-assembly ability of collagen[1].
