Description

Dnp-Peg4-Alcohol CAS NO 1807520-99-5 is a specialized bifunctional chemical linker featuring a dinitrophenyl (DNP) group and a tetraethylene glycol (PEG4) spacer terminated with a primary alcohol. This compound is engineered to facilitate the conjugation of biomolecules, offering a controlled and stable linkage. It is primarily utilized by researchers and manufacturers in the fields of bioconjugation, proteomics, and pharmaceutical development for creating targeted drug delivery systems, diagnostic assays, and advanced research reagents.

Application

• Bioconjugation Reagent: Used for coupling peptides, proteins, or antibodies to surfaces, nanoparticles, or other molecules via its reactive alcohol and DNP groups.
• Proteomics Research: Serves as a versatile linker in the synthesis of activity-based probes (ABPs) or affinity tags for studying protein function and interactions.
• Drug Delivery System Development: Incorporated into the design of antibody-drug conjugates (ADCs) or other targeted therapeutics to provide a cleavable or stable PEGylated linkage.
• Diagnostic Assay Fabrication: Employed in the development of immunoassays and biosensors for attaching detection labels or capture molecules.
• Material Science & Surface Functionalization: Applied to modify material surfaces with bioactive molecules for cell culture, tissue engineering, or sensor applications.
• Crosslinking Agent: Acts as a heterobifunctional crosslinker for connecting two different entities in biochemical and biophysical studies.
