Tide Quencher™ 7WS amine
TQ7WS amine
TQ7WS is designed to be a superior quencher to Cy7, TF7 and Alexa Fluor 750. TQ7WS has (a). much stronger absorption; (b). much higher quenching efficiency; and (c). versatile reactive forms with desired solubility for labeling oligonucleotides and peptides. This TQ7WS product is primarily used for labeling the small molecules that contain a carbonyl group.
