5(6)-TAMRA cadaverine is widely used in biochemical and cellular research as a fluorescent labeling agent. Its primary application is in the study of protein interactions, cellular processes, and molecular dynamics due to its bright fluorescence and stability. It is particularly useful in fluorescence microscopy, flow cytometry, and fluorescence resonance energy transfer (FRET) experiments. Additionally, it serves as a marker in tracking and visualizing biomolecules within live or fixed cells, aiding in the understanding of intracellular transport and localization. Its versatility also extends to labeling peptides, antibodies, and other biomolecules for diagnostic and research purposes.
