BDP TR is a borondipyrromethene dye which has absorption and emission wavelengths close to Texas Red (ROX) dye. The fluorophore is bright, moderately hydrophobic, and has low molecular weight. An extra linker based on aminocaproic acid (C6) provide better separation between the dye, and the biomolecule.
The NHS ester function can be used for the conjugation with proteins, peptides, and other molecules possessing amine group.
