Product Information Molecular Structure

Fmoc-amino-modifier III CEP

Notes: This phosphoramidite is For installation of an Fmoc protected amino group internally or at the 5-end of an oligonucleotide.


The (fluorenylmethyl)carbamoyl (Fmoc) group has been shown to be useful as such an amine protecting group for amine modification of oligonucleotides.1 It is removed during cleavage/deprotection with ammonium hydroxide. Our new Fmoc-amino Modifier III (BA 0335) contains a 1,3,5-triol framework which serves two functions. First, extended framework disfavors cyclic phosphate formation when the DMT group is removed, thereby minimizing loss of the amine modification. Second, the 1,3,5-triol framework maintains the natural 3-carbon atom internucleotide phosphate distance. 1

We also offer a version of such an Fmoc-protected amino-modifier for installation of an amino group at the 3'-terminus, i.e., 3'-Fmoc-amino-modifier CPG, in both higher- and lower-loaded versions, namely BA 0299 (500 CPG) and BA 0307 (1000 CPG). It features a 7-atom spacer between the amino group and the O-DMT group.
