Product Information Molecular Structure

Fmoc-amino-modifier-C6-dT CEP

Notes:  Phosphoramidite for incorporation of a nucleobase-tethered amine that can be deprotected prior to cleaving the oligonucleotide from the solid support.

Description: The (fluorenylmethyl)carbamoyl (Fmoc) group has been shown to be a useful amine protecting group for amine modification of oligonucleotides.1 It is removed during cleavage/deprotection with ammonium hydroxide. Alternatively, the Fmoc group can be removed before cleavage of the oligonucleotide from the solid support,2 e.g., with piperidine, simplifying the acylation process. After the acylation is complete, the labeled oligonucleotide can then be cleaved from the support and further deprotected with ammonium hydroxide.

For applications requiring a nucleobase-tethered amine at internal or 5' positions, we offer the new Fmoc-protected compound Fmoc-Amino-Modifier-C6-dT CEP (BA 0287), which offers the possibility of on-bead acylation as discussed above. It is an alternative to the venerable Amino-Modifier-C6-dT CEP (BA 0015), which bears a trifluoroacetyl (TFA) protecting group. The TFA group cannot be removed without cleavage of the oligonucleotide from the resin.
