Tide Fluor™ 5WS maleimide [TF5WS maleimide] *Superior replacement for Cy5*

Tide Fluor™ 5WS (TF5WS) family has the spectral properties essentially identical to those of Cy5. Compared to Cy5 probes TF5WS family has much stronger fluorescence and higher photostability. Additionally their fluorescence is pH-independent from pH 3 to 11. These characteristics make this new dye family a superior alternative to Cy5. TF5WS-labeled peptides and nucleotides exhibit much stronger fluorescence and higher photostability than the ones labeled with Cy5. In pairing with our Tide Quencher™ 5WS (TQ5WS), a variety of FRET peptides and nucleotides can be developed for detecting proteases and molecular beacons with enhanced sensitivity and stability. This TF5WS product is used for post-labeling of thiol-modified oligonucleotides and and cysteine-containing peptides.

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.
