    Complete ligation adaptor sequences

    Hello everyone,

    I am producing Ion Torrent sequencing libraries both using the ligation based library kit and the ampliseq strategy. The only adaptor sequences I can find from Lifetech are the ones involved in ampliseq:

    Forward primer (Primer A-key):
    5’-CCATCTCATCCCTGCGTGTCTCCGACTCAG-template-specific-sequence-3’
    Reverse primer (Primer P1-key):
    5’-CCTCTCTATGGGCAGTCGGTGAT-template-specific-sequence-3’

    For quantitation purposes I use the Taqman based qPCR kit. This is however only possible with the ligated libraries. On this basis I assume the double stranded oligos used for ligation contains a longer sequence, than the one generated in the ampliseq PCR.

    Does anyone have this sequence of the ligation adaptors?

    I know this may well, for some obscure reason, be one of Lifetechs little secrets and that I may have to go through the trouble of cloning and sequencing the adaptors myself.

    Exactly what I was looking for! Thank you very much genseq!

      Hi Apex,

      The sequences of the fragment library adaptors can be found in Appendix D (pp. 45) of the current Ion Xpress™ Plus gDNA Fragment Library Preparation User Guide, as available on the Ion Community.

      Ion AmpliSeq™ Custom Panels may be designed using the Ion AmpliSeq™ Designer website.

        adaptor sequences for Ion S5

        Hi,
        I'm new to Life Tech semi conductor Sequencing and only have MiSeq experience. We were offered a demo run of the Ion S5 and I would like to produce the library beforehand with our custom protocol.

        Can anyone tell me if the Ion torrent adaptors are the same for the Ion S5?

        Fwd: CCATCTCATCCCTGCGTGTCTCCGACTCAG

        Rev: CCTCTCTATGGGCAGTCGGTGAT

        cheers,
        JoF

          Multiomic Liquid Biopsy: What DNA/RNA Panels Reveal That DNA Alone Can’t
          by SEQadmin2



          Tumors contain complex mixtures of cell populations that evolve in response to treatment and host-specific factors. Tissue biopsies provide only static snapshots of a tumor’s state. But what if we could follow that evolution over time using a minimally invasive technique?

          Liquid biopsies can detect tumor-derived material circulating in the bloodstream, providing a way to study treatment response, detect emerging resistance, and discover new biomarkers. Circulating

          New Genomics Technologies Take Aim at Long-Standing Limits
          by SEQadmin2


          Researchers using sequencing and genomics tools often have to make trade-offs. They can choose between speed or scale, short reads or long-range information, or targeted panels or a view of the whole transcriptome. New technologies that have been released this year are built to address those tough choices.

          We asked six companies the same four questions to learn about their latest products. The new technologies bring a lot to the table, including rethinking sequencing
