  • This special DNA phosphoramidite with a C8-Spacer between the reactive alkyne group and the backbone is used under standard conditions for solid phase synthesis of oligonucleotides. It has shown to be incorporated into DNA oligomers with excellent coupling efficiency and subsequent use of those oligonucleotides in click reactions is achieved using our different azide labels.
