Tide Quencher™ 4WS amine
TQ4WS amine
TQ4WS is designed to be a superior quencher to ROX, TF4 and Texas Red®. TQ4WS has (a). much stronger absorption; (b). much higher quenching efficiency; and (c). versatile reactive forms with desired solubility for labeling oligonucleotides and peptides. This TQ4WS product is primarily used for labeling the small molecules that contain a carbonyl group.
