Tide Fluor? 8WS, succinimidyl ester [TF8WS SE]*Near Infrared Emission*

Tide Fluor? 8WS (TF8WS) family has the spectral properties similar to those of IRDye 800. 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 TF8WS-labeled peptides and nucleotides exhibit stronger fluorescence and higher photostability than the ones labeled with  IRDye 800. In pairing with our Tide Quencher? 8WS (TQ8WS), a variety of FRET peptides and nucleotides can be developed for detecting proteases and molecular beacons with enhanced sensitivity and stability.
