Tide Fluor™ 8WS azide [TF8WS azide] *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 TF7-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. This TF8WS product is reactive to alkynes, and useful for click chemistry.
