DusQ 21 is a quencher for the dyes in far red region of the spectrum. The dye is a xanthene derivative, unlike DusQ 1 or DusQ 2, that are azo dyes. It has a high extinction coefficient, and provides an outstanding quenching efficiency.
The controlled pore glass solid support allows to synthesize oligonucleotides carrying the dye moiety on 3’-terminus.
We recommend the use of ultramild, phenoxyacetyl protected monomers. As an alternative, post-synthetic labeling using NHS ester of DusQ 21 quencher can be used.
Usage
Coupling: Standard conditions identical to normal nucleobases.
Deprotection: 2 hours at room temperature using concentrated ammonia or potassium carbonate K2CO3 (50 mM solution in methanol).
