Tide Quencher™ 4WS azide
TQ4WS azide
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 reactive to alkynes, and useful for click chemistry.
<p>Click chemistry is a method for attaching a&nbsp;probe&nbsp;or&nbsp;substrate&nbsp;of interest to a specific biomolecule, a process called&nbsp;bioconjugation. The possibility of attaching dyes&nbsp;and other&nbsp;reporter molecules&nbsp;has made click chemistry a very powerful tool for identifying, locating, and characterizing both old and new biomolecules. The classic click reaction is the copper-catalyzed reaction of an&nbsp;azide&nbsp;with an&nbsp;alkyne&nbsp;to form a 5-membered&nbsp;heteroatom&nbsp;ring, this reaction is commonly called Cu(I)-Catalyzed Azide-Alkyne&nbsp;Cycloaddition&nbsp;(CuAAC).</p>
