Tide Fluor™ 4 maleimide [TF4 maleimide] *Superior replacement for ROX and Texas Red*

TF4 is designed to be a superior fluorophore alternative to ROX and Texas Red®. TF4 has (a). stronger fluorescence intensity; (b). higher conjugation yield; and (c). longer shelf life. Additionally their fluorescence is pH-independent from pH 3 to 11. These characteristics make this new dye family a superior alternative to ROX and Texas Red®. In pairing with our Tide Quencher™ 4 (TQ4), a variety of FRET peptides and nucleotides can be developed for detecting proteases and molecular beacons with enhanced sensitivity and stability. This TF4 product is is used for post-labeling of thiol-modified oligonucleotides and peptides that contain cysteines.

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.
