Biotin-PEG7-amine is widely used in bioconjugation and biochemical research due to its unique properties. The biotin moiety allows for strong binding with avidin or streptavidin, making it valuable in affinity purification, immunoassays, and diagnostic applications. The PEG7 spacer enhances solubility and reduces steric hindrance, improving the efficiency of biotinylation reactions. This compound is commonly employed in labeling proteins, peptides, and other biomolecules for detection and analysis in techniques like ELISA, flow cytometry, and microscopy. Additionally, it is utilized in drug delivery systems to create targeted therapies by conjugating with specific biomolecules. Its versatility and effectiveness make it a crucial tool in both research and clinical settings.
