Tide Fluor(TM) 3WS acid (TF3 acid) *Superior replacement to Cy3*

Tide Fluor(TM) 3WS (TF3WS) family has the spectral properties essentially identical to those of Cy3. Compared to Cy3 probes TF3WS family has better water solubility. It has been used to label the hydrophobic peptides that hasve poor water solubility. Additionally their fluorescence is pH-independent from pH 3 to 11. These characteristics make this new dye family a superior alternative to Cy3. In pairing with our Tide Quencher(TM) 3 (TQ3), a variety of FRET peptides and nucleotides can be developed for detecting proteases and molecular beacons with enhanced sensitivity and stability.
