This compound is widely used in bioconjugation and labeling applications due to its multifunctional properties. The TAMRA fluorophore enables fluorescence imaging, making it valuable for tracking and visualizing biomolecules in cellular and molecular studies. The azide group allows for click chemistry reactions, particularly copper-catalyzed azide-alkyne cycloaddition (CuAAC), facilitating precise and efficient conjugation with alkyne-containing molecules. The PEG (polyethylene glycol) spacer enhances solubility, reduces nonspecific interactions, and improves biocompatibility, making it suitable for in vivo and in vitro applications. The biotin moiety enables strong and specific binding to avidin or streptavidin, which is useful for purification, detection, and immobilization processes in assays like ELISA, pull-down assays, and affinity chromatography. Together, these features make it a versatile tool in proteomics, drug delivery, and diagnostic research.
