DNP-PEG4-NHS Ester（Cat No.:I015857）is a heterobifunctional PEG reagent with a 2,4-dinitrophenyl (DNP) group and an active N-hydroxysuccinimide (NHS) ester, connected by a PEG₄ spacer. The DNP moiety acts as a hapten or antigenic determinant, widely used in immunology studies, antibody development, and assay design. The NHS ester reacts efficiently with primary amines under mild conditions to form stable amide bonds, enabling site-specific conjugation of biomolecules. The PEG₄ chain enhances solubility, flexibility, and biocompatibility. This reagent is valuable for bioconjugation, immunoassay development, and targeted functionalization applications.
