Tide Quencher™ 6WS azide [TQ6WS azide]

TQ6WS is designed to be a superior quencher to Cy5.5, TF6 and Alexa Fluor 680. TQ6WS has (a). much stronger absorption; (b). much higher quenching efficiency; and (c). versatile reactive forms with desired solubility for labeling oligonucleotides and peptides. This TQ6WS product is reactive to alkynes, and useful for click chemistry.
