Tide Quencher™ 4WS amine

TQ4WS amine

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 primarily used for labeling the small molecules that contain a carbonyl group.

<p>Dye amines are the most popular tool for conjugating dyes to a target compound with a carbonyl group (e.g., aldehyde, carboxylic acid or activated carboxy group such as NHS ester).</p>
