Tide Quencher™ 5WS acid
TQ5WS acid
TQ5WS is designed to be a superior quencher to Cy5, TF5 and Cy5.5. TQ5WS has (a). much stronger absorption; (b). much higher quenching efficiency; and (c). versatile reactive forms with desired solubility for labeling oligonucleotides and peptides. This TQ5WS product is primarily used for labeling peptides.
<p>Dye quencher acids are the common tools for conjugating dyes to a peptide, protein, antibody, amino-modified oligonucleotide or nucleic acid through their amino groups. They are the excellent building blocks for developing FRET assays.</p>
