    Abstract: Methods, Compositions, and Systems are provided for nucleic acid sequencing where the sequential incorporation of nucleotides uses two distinct chemical steps. A plurality of nucleotide analogs, each having a labeled leaving group at its 3? hydroxyl can be sequentially added to a growing strand in the presence of a selective cleaving activity that cleaves the 3? hydroxyl leaving group preferentially after it has been incorporated. The selective cleaving agent can comprise an exonuclease activity, and the exonuclease activity can be a polymerase-associated exonuclease activity. Nucleotide analogs having labels on both a cleavable polyphosphate portion and on a 3? hydroxyl leaving group can provide signals characteristic of nucleotide analog incorporation. Systems having illumination optics, collection optics, and substrates observe signals from the labels as they are being incorporated into a growing nucleic acid strand, allowing for the sequencing of template nucleic acids.

  • Patent number: 8304529
    Abstract: Novel cap analogs which are easily synthesized, resulting in high levels of capping efficiency and transcription and improved translation efficiencies are provided. Such caps are methylated at the N7 position of one or both guanosines of the dinucleotide cap as well as at the 3? position on the ribose ring. Substituent groups on the ribose ring also result in the cap being incorporated in the forward orientation. Also provided are methods useful for preparing capped analogs and using mRNA species containing such analogs are also contemplated herein, as well as kits containing the novel cap analogs.

  • Patent number: 8278425
    Abstract: Provided herein are bicyeMc nucleosides comprising a substituted amino group in the bridge, oligomeric compounds having at least one of these bicyclic nucleosides and methods of using the oligomeric compounds. The bicyclic nucleosides comprising a substituted amino group in the bridge are useful for enhancing properties of oligomeric compounds including nuclease resistance, in certain embodiments, the oligomeric compounds hybridize to a portion of a target RNA resulting in loss of normal function of the target RNA.

  • Patent number: 8278283
    Abstract: The present disclosure describes 6-disubstituted bicyclic nucleosides, oligomeric compounds prepared therefrom and methods of using the oligomeric compounds. More particularly, the 6-disubstituted bicyclic nucleosides each comprise a 2?-O—C(Ri)(R2)-4? or 2?-O—C=(R3)(R.4)-4? bridge wherein each R is, independently a substituent group and Ri and R2 include H. The 6-disubstituted bicyclic nucleosides are useful for enhancing properties of oligomeric compounds including nuclease resistance. In certain embodiments, the oligomeric compounds provided herein hybridize to a portion of a target RNA resulting in loss of normal function of the target RNA.
