Used in bioconjugation techniques to link biomolecules with other entities, enhancing solubility and stability. Commonly applied in drug delivery systems to improve the targeting efficiency of therapeutic agents. Facilitates the attachment of biotinylated compounds to streptavidin or avidin, useful in immunoassays and diagnostic kits. Employed in the development of biosensors for detecting specific biological interactions. Utilized in research for labeling proteins, peptides, and nucleic acids to study their functions and interactions. Enhances the performance of biotin-streptavidin binding in molecular recognition studies.
