BA 0269
Product Information Molecular Structure

5-Aminoallyl-U CEP

Notes: This phosphoramidite allows the introduction of a 5-aminoallyluridine residue into oligonucleotides for the purpose of post-synthetic labeling by acylation.

Description: To our knowledge, 5-Aminoallyl-U CEP does not appear in the literature. However, the 2'-deoxyribo version (5-Aminoallyl-dU CEP) is known1,2 and is also offered by Berry & Associates (see Product Number BA 0311). It should be noted that the 2'-deoxy version is useful not only in amine modification, but in triplex-forming oligonucleotides (TFOs) that are similar in stability to those bearing unmodified residues.2

1. Early work on the introduction of a 5-aminoallyl-dU amino modifier into oligonucleotides involved the methyl phosphoramidite.1a 5-Aminoallyl-dU CEP (our BA 0311), employing a 2-cyanoethyl phosphoramidite, was reported later.1b See: (a) Cook, A. F.; Vuocolo, E.; Brakel, C. L. Nucleic Acids Res. 1988, 16, 4077-4095. (b) Lermer, L.; Yoann, R.; Ting, R.; Perrin, D. M. J. Am. Chem. Soc. 2002, 124, 9960-9961.
