Application

5(6)-Carboxytetramethylrhodamine (TAMRA, TMR) may be used as a fluorescence probe to study the distribution of molecules such as cell-penetrating peptides (CPPs) and as fluorescence partner in applications such as two-dimensional fluorescence intensity distribution analysis (2D-FIDA), luminescence resonance energy transfer (LRET) and fluorescence resonance energy transfer (FRET).
Reacts with primary and secondary amine groups on proteins, nucleic acids and other biomolecules.

Some of the most serious diseases are characterized by the presence of a specific secondary structure within DNA or RNA, often in the promoter or the coding region of the responsible gene, that enhances or disrupts expression of the protein.

Investigation of interactions between hydrophobic model peptides and lipid bilayers is perhaps the only way to elucidate the principles of the folding and stability of membrane proteins (White, S. H., and Wimley, W. C. (1998) Biochim. Biophys. Acta 1367, 339-352).
