Tide Fluor™ 7WS acid [TF7WS acid] Superior replacement for Cy7

Tide Fluor™ 7WS (TF7WS) family has the spectral properties similar to those of Cy7, IRDye 800 and Alexa Fluor 750. Their fluorescence is pH-independent from pH 3 to 11. These characteristics make this new dye family more robust to pH-sensitive assays. In some cases TF7-labeled peptides and nucleotides exhibit stronger fluorescence and higher photostability than the ones labeled with Cy7, IRDye 800 and Alexa Fluor 750. In pairing with our Tide Quencher™ 7WS (TQ7WS), a variety of FRET peptides and nucleotides can be developed for detecting proteases and molecular beacons with enhanced sensitivity and stability.
