Tide Fluor(TM) 4 acid [TF4 acid] *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.
