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. This TQ8WS product is used for post-labeling of thiol-modified oligonucleotides and peptides that contain cysteines.

Figure 1. Fluorescent dye maleimides are the most popular tool for conjugating dyes to a peptide, protein, antibody, thiol-modified oligonucleotide or nucleic acid through their SH group. Maleimides react readily with the thiol group of proteins, thiol-modified oligonucleotides, and other thiol-containing molecules under neutral conditions. The resulting dye conjugates are quite stable.
