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

Figure 1. Click chemistry is a method for attaching a probe or substrate of interest to a specific biomolecule, a process called bioconjugation. The possibility of attaching dyes and other reporter molecules 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 azide with an alkyne to form a 5-membered heteroatom ring, this reaction is commonly called Cu(I)-Catalyzed Azide-Alkyne Cycloaddition (CuAAC).
