DusQ2 is a black quencher dye for the synthesis of dual labeled oligonucleotide probes for qPCR bearing 5′-quencher. This quencher is ideal for HEX, JOE, ROX, Cyanine5 and other dyes with the emission in orange and red part of the spectrum.

The primary phosphoramidite group couples with hydroxyls efficiently in oligonucleotide synthesis.

DusQ2 是一种黑色猝灭剂染料,用于合成带有 5′-猝灭剂的 qPCR 的双标记寡核苷酸探针。 这种猝灭剂非常适合 HEX、JOE、ROX、Cyanine5 和其他在光谱的橙色和红色部分发射的染料。
