Abstract

Sequence specific phosphorothioate oligonucleotides comprising nucleoside units which are joined together by either substantially all Sp or substantially all Rp phosphorothioate intersugar linkages are provided. Such sequence specific phosphorothioate oligonucleotides having substantially chirally pure intersugar linkages are prepared by enzymatic synthesis from nucleoside 5'"'"'-O-(1-thiotriphosphates).

Claims

1. An oligonucleotide represented by SEQ ID NO:

4, wherein at least 75% of the nucleoside units are joined together by Sp phosphorothioate 3'"'"' to 5'"'"' linkages.

3. The oligonucleotide of claim 1, wherein all of the internucleoside linkages are joined together by Sp phosphorothioate 3'"'"' to 5'"'"' linkages.

5. A composition containing an oligonucleotide of claim 1 and an acceptable carrier.

2. An oligonucleotide represented by SEQ ID NO:

4, wherein at least 75% of the nucleoside units are joined together by Rp phosphorothioate 3'"'"' to 5'"'"' linkages.

4. The oligonucleotide of claim 2, wherein all of the internucleoside linkages are joined together by Rp phosphorothioate 3'"'"' to 5'"'"' linkages.

6. A composition containing an oligonucleotide of claim 2 and an acceptable carrier.
