spacer 18 Phosphoramidite Chemical Properties,Usage,Production

Description

Spacer phosphoramidite 18 (hexaethylene glycol phosphoramidite) is an amidite reagent for oligonucleotide synthesis. It provides a long hydrophilic linker that can be used for the synthesis of Scorpion-type qPCR probes, for spacing biotin from oligo strand, and for other applications requiring spatial separation of modifier and oligo

Uses

Hexaethylene glycol phosphoramidite (Spacer Phosphoramidite 18) is an amidite reagent for oligonucleotide synthesis. Hexaethylene glycol phosphoramidite can be used as a linker in synthesis of nucleotide chain and qPCR probes[1][2].
