Tide Quencher(TM) 7 succinimidyl ester (TQ7 SE)

TQ7 is designed to be a superior quencher to Cy7, TF7 and Alexa Fluor 750. TQ7 has (a). much stronger absorption, (b). much higher quenching efficiency, and (c). versatile reactive forms with desired solubility for labeling oligonucleotides and peptides. This TQ5 product is primarily used for post-labeling of amino-modified oligonucleotides and the N-terminal or lysine residues of peptides.
