TAMRA-PEG3-Azide is widely used in bioimaging and bioconjugation due to its fluorescent properties and reactive azide group. It serves as a valuable tool in labeling biomolecules, such as proteins, peptides, and nucleic acids, enabling their visualization and tracking in cellular and molecular studies. The azide group allows for efficient click chemistry reactions, particularly with alkyne-modified compounds, facilitating the creation of stable covalent bonds. This makes it highly effective in the development of fluorescent probes, drug delivery systems, and diagnostic assays. Its PEG spacer enhances solubility and reduces steric hindrance, improving the efficiency of conjugation processes. Applications extend to research in cancer biology, drug discovery, and live-cell imaging, where precise and specific labeling is crucial.
