Caractéristiques et avantages

dPEG4 biotin acid consists of biotin and a propionic acid-functionalized tetraethylene glycol derivative. Numerous functional or reactive groups can modify the terminal acid moiety, including the acylating agents N-hydroxysuccinimide (NHS) and 2,3,5,6-tetrafluorophenol (TFP). Also, dPEG4 biotin acid reacts directly with primary amines using a suitable carbodiimide such as 1-Ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC). The amphiphilic dPEG linker gives biotin excellent solubility in water and aqueous buffer, where biotin usually is poorly soluble. dPEG4 biotin acid offers significantly superior solubility and performance characteristics compared to the traditional, highly hydrophobic biotinylation reagent known as LC-biotin. Moreover, although dPEG4 biotin acid and LC-biotin have comparable linker lengths, dPEG4 biotin acid will not trigger the aggregation and precipitation of conjugated biomolecules, even at high levels of biotin incorporation on the biomolecule. In contrast, LC-biotin triggers the aggregation and precipitation of biomolecules with the incorporation of a few LC-biotin groups onto the biomolecule.

The need to develop label-free biosensing devices that enable rapid analyses of interactions between small molecules/peptides and proteins for post-genomic studies has increased significantly. We report a simple metal-insulator-metal (MIM) geometry for fabricating a highly sensitive detection platform for biosensing.

The utility of catalyst-free azide-alkyne [3 + 2] cycloaddition for the immobilization of a variety of molecules onto a solid surface and microbeads was demonstrated. In this process, the surfaces are derivatized with aza-dibenzocyclooctyne (ADIBO) for the immobilization of azide-tagged
