This modified support with a pore size of 500 Å is intended for the synthesis of oligonucleotides of up to 50 bases in length modified with non-fluorescent DusQ 1 quencher at the 3′ end.
DusQ 1 dark quencher exhibits the strongest absorption within the range of 480 to 580 nm; its absorption maximum is at 534 nm. It can be used for combined quenching (a combination of static and dynamic quenching) of many fluorophores, including Biosearch Blue™, Marina Blue™, Edans, Bothell Blue, FAM™, JOE™, VIC™, R6G, HEX™, TET™, CAL Fluor™ Gold 540, and Yakima Yellow™. It can be used for the synthesis of hybridization probes such as TaqMan, Molecular Beacon, Scorpion.
Usage
Coupling: Standard conditions identical to normal nucleobases.
Deprotection: 2 hours at room temperature using concentrated ammonia or 10 min at 65 °C using AMA mixture, concentrated aqueous ammonia/40% methylamine (1:1). Deprotection conditions depend on oligonucleotide composition and nucleobase protecting groups, as well as additional modifications, if present.
