Tide Quencher(TM) 3WS succinimidyl ester (TQ3WS SE)

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. This TQ3 product is primarily used for labeling peptides. It is also used for post-labeling of amino-modified oligonucleotides.
