Tide Quencher(TM) 4 succinimidyl ester (TQ4 SE)

TQ4 is designed to be a superior quencher to ROX, TF4 and Texas Red(R). TQ4 has (a). much stronger absorption, (b). much higher quenching efficiency, and (c). versatile reactive forms with desired solubility for labeling oligonucleotides and peptides. This TQ4 product is primarily used for labeling peptides. It is also used for post-labeling of amino-modified oligonucleotides.
