Tide Quencher™ 2 alkyne
TQ2 alkyne
TQ2 is designed to be a superior quencher to FAM, HEX, TET, JOE, TF2 and rhodamine 6G. TQ2 has (a). much stronger absorption; (b). much higher quenching efficiency; and (c). versatile reactive forms with for labeling oligonucleotides and peptides. This TQ2 product is reactive to azides, and useful for click chemistry. For the applications that require good water solubility, we recommend that you use TQ2WS that has much higher water solubility than TQ2.
<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>
