Oligonucleotides prepared using 5’-Hexynyl Phosphoramidite are stable to standard deprotection conditions and exhibit a slightly increased retention time on RP HPLC. Azides are not compatible with oligonucleotide synthesis using phosphoramidites so a post-synthesis reaction is required. Azidobutyrate NHS Ester is used1 for azido-modification of amines at either the 3’-end or the 5’-end of an oligo and it can even be used for internal modification on an Amino-Modifier-C6 dX residue within the sequence. Specific to the 5’-terminus, 5’-Bromohexyl Phosphoramidite is added in the last cycle. This modifier can then be easily transformed into a 5’-azido group by displacement of bromide using sodium azide.2 Alkyne NHS ester allows the functionalization of an amino moiety in a variety of molecules, including DNA and RNA oligonucleotides as well as peptides or proteins. We also offer a synthesis support for labelling the 3’ terminus of oligonucleotides with an alkyne group for use in Click Chemistry. This builds upon our 1,3-diol product portfolio with the serinol backbone. A 5’-iodo-modified oligonucleotide (prepared using 5’-Iodo-dT) can be quantitatively converted to the corresponding 5’-azide.
