LC-LC-()-Biotin is widely used in biochemical and molecular biology research due to its biotinylation properties. It is commonly employed for labeling proteins, peptides, and other biomolecules, enabling their detection and purification through biotin-streptavidin interactions. This compound is particularly useful in immunoassays, such as ELISA, where it enhances sensitivity and specificity. Additionally, it plays a critical role in affinity chromatography, facilitating the isolation of target molecules from complex mixtures. Its applications also extend to cell surface labeling and imaging studies, where it helps in visualizing cellular components and processes.
