Tide Fluor(TM) 4 amine [TF4 amine] *Superior replacement for ROX and Texas Red*

TF4 is designed to be a superior fluorophore alternative to ROX and Texas Red®. TF4 has (a). stronger fluorescence intensity, (b). higher conjugation yield, and (c). longer shelf life. Additionally their fluorescence is pH-independent from pH 3 to 11. These characteristics make this new dye family a superior alternative to ROX and Texas Red®. In pairing with our Tide Quencher(TM) 4 (TQ4), a variety of FRET peptides and nucleotides can be developed for detecting proteases and molecular beacons with enhanced sensitivity and stability. This TF4 product is primarily used for labeling the small molecules that contain a carbonyl group.
