General description

DMT-dC(tac) Phosphoramidite is a TAC Protected Phosphoramidite. Substitution of standard protecting groups with the labile TAC (tert.-butylphenoxyacetyl) protecting group results in ultra-fast and easy deprotection under mild conditions, suitable for oligonucleotides with base labile monomers and reporters as well as in-situ synthesis schemes on glass surfaces.

Other Notes

  • The deprotection of oligonucleotide synthesis products with the AMAreagent is ultra-fast: complete deprotection requires 10 minutes at 65 °C
  • Side reactions at C-monomers through transamination are eliminated
  • Not compatible with some base-labile modified nucleosides
  • dC(tac)-phosphoramidite can directly substitute for dC(bz)-phosphoramidite
  • No change is required in the reagents commonly used for DNA synthesis.Acetonitrile is used to dissolve phosphoramidite. The standard aceticanhydride capping reagent can be employed.
