DusQ 1 phosphoramidite is a true dark quencher with broad absorption curve which covers the visible spectrum with maximum in green to yellow region. It is used for the synthesis of dual labeled oligonucleotide probes for qPCR bearing 5'-quencher DusQ 1 and other FRET applications for multiplexing assays. Contains a DMT protection of the hydroxymethyl group, which allows oligonucleotide purification on cartridges.
DusQ 1 has a quenching range (QR) 480 - 580 nm to construct efficiently quenched qPCR probes paired with all common reporter dyes such as FAM, TET, JOE, HEX and Cyanine3 with high quenching efficiency, and form completely non-fluorescent complexes.
Usage
Coupling: 6 minutes coupling time recommended.
Deprotection: for 2 h at RT using ammonium hydroxide, or 10 min at 65 °C with AMA (solution of 30% ammonium hydroxide/40% aqueous methylamine 1:1 v/v).
Deprotection time depends on oligonucleotide composition and nucleobase protecting groups, and additional modifications.
