Description

Biotin-Dpeg(R)11-Lipoamide CAS NO 960069-81-2 is a high-purity, heterobifunctional crosslinking reagent designed for advanced bioconjugation applications. This compound is engineered to provide a stable, long-chain PEG spacer that bridges biotin and a reactive lipoamide group, enabling precise and efficient labeling of biomolecules. It is an essential tool for researchers and manufacturers in the fields of pharmaceutical development, diagnostic assay production, and advanced materials science, where controlled protein modification and surface functionalization are critical.

Application

• Bioconjugation and Protein Labeling: Used to attach biotin tags to proteins, antibodies, or peptides via the reactive lipoamide moiety for detection or purification.
• Diagnostic Kit Development: Serves as a key component in the manufacture of ELISA, lateral flow assays, and other immunoassays requiring stable biotin-streptavidin interactions.
• Drug Delivery System Fabrication: Facilitates the surface functionalization of nanoparticles, liposomes, and other drug carriers for targeted delivery.
• Affinity Chromatography Resin Production: Used to create biotinylated surfaces or ligands for the purification of biomolecules.
• Biomaterial and Biosensor Surface Modification: Enables the controlled immobilization of biomolecules on chips, electrodes, and other substrates.
• Research Reagent: A critical tool in academic and industrial R&D for studying protein interactions, cellular processes, and signal transduction pathways.
