Description

4'-Azidoazobenzene-4-Oxysuccinimide Ester is a specialized heterobifunctional crosslinking reagent featuring a photoactivatable azido group and an amine-reactive NHS ester. This compound matters for its ability to facilitate the covalent conjugation of biomolecules under mild, controlled conditions using UV light. It is primarily needed by researchers and manufacturers in the fields of bioconjugation, proteomics, and materials science for labeling, immobilization, and surface functionalization applications.

Application

• Photoaffinity labeling of proteins, peptides, and nucleic acids for interaction studies.
• Surface modification and functionalization of polymers, nanoparticles, and biosensors.
• Preparation of antibody-drug conjugates (ADCs) and other targeted therapeutic constructs.
• Crosslinking agent for the development of advanced hydrogel and biomaterial networks.
• Immobilization of ligands or capture molecules on solid supports for assay development.
• Proteomic research tools for identifying protein-protein interactions and mapping binding sites.
