Tide Quencher™ 1 acid
TQ1 acid
TQ1 is designed to be a superior quencher alternative to DABCYL. Compared to DABCYL, TQ1 have (a). much stronger absorption; (b). much higher quenching efficiency; and (c). versatile reactive forms with desired solubility for labeling oligonucleotides and peptides. This TQ1 product is primarily used for labeling peptides.
<p>With EDAC or other equivalent activating coupling agents, dyes can react readily with the primary amines (R-NH<sub>2</sub>) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. The resulting dye conjugates are quite stable.</p>
