TR is a sulfonated analog of ROX dye with similar spectral properties and emission in the red region of the spectrum. This derivative is a dye with an aminohexanoic acid linker that provides spacing between the fluorophore and the biomolecule to prevent undesired interactions.
TR carboxylic acid is a non-reactive form of TR dye that can be used as a reference standard in experiments involving TR dye conjugates. Besides, the carboxylic group can react with hydrazines, hydroxylamines, and amines after activation by carbodiimides such as EDAC.
