Tide Quencher(TM) 3WS acid (TQ3WS acid)

TQ3WS is designed to be a superior quencher to TAMRA, TF3 and Cy3. TQ3WS has (a). much stronger absorption, (b). much higher quenching efficiency, (c). good water solubility, and (d). versatile reactive forms with desired solubility for labeling oligonucleotides and peptides. Like TQ3, this TQ3WS product is used for post-labeling of thiol-modified oligonucleotides and and cysteine-containing peptides. TQ3WS has much higher water solubility than TQ3.
