The first step in decoding these genetic messages is to copy part of the nucleotide sequence from DNA into RNA, or ribonucleic acid.

Another paper3 describes a method for the inactivation of micro RNA (miRNA) that may help to elucidate their functions. It uses 2’-OMe-RNA oligonucleotides (23-mers, complementary to a target miRNA) with a cholesteryl group at the 3´terminus and phosphorothioates at positions 1 and 2 at the 5´end and at the last four positions at the 3´end. These oligos are called antagomirs. These molecules promote the cleavage of complementary miRNAs and thus should allow analysis of their function. The role of the PS linkages presumably is the stabilization against degradation in the mouse experiments as it is standard in the antisense field in such in vivo situations. And finally, a recent paper4 shows that PS does not systematically abolish siRNA activity, opening the way for some potentially less expensive stabilization of such molecules. Incorporation of 2’-OMe (in the sense strand) in combination with PS linkages should confer to siRNA increased resistance to degradation by nucleases, as well as prolonged serum retention. And it is also possible that such easy modification of siRNA may increase the specificity by eliminating sense strand recruitment in the RISC complex and thus reducing a source of off-target effect.

Gene Link also offers custom synthesis of RNA and DNA chimeric oligos withinvestigator specified ribo or deoxy bases or 2’-O-methyl bases. The chimericoligos can also be synthesized with the regular phoshodiester bonds orsubstituted with phosphorothioate linkages. The combination of 2’-O- methylRNA bases with phosphorothioate internucleotide linkages imparts these oligosgreater nuclease resistance which is particularly useful for antisense studies(please refer to our technical sheet on Antisense Oligonucleotides for othermodifications). Custom phosphorothioate oligonucleotides synthesized by GeneLink can be specified to have all the diester bonds substituted or only someselected diester linkages depending upon the researchers experimentalrequirement. Substitution of all diester linkage is recommended to providegreater nuclease resistance.
