    Indexed RADseq P2-adaptor sequences

    I have successfully used the original single-digest RADseq protocol in the past. Quickly: this protocol digests individual DNA with a single RI (commonly Sbf1). Then, P1-adaptors (each containing a unique barcode to mark individual DNA) are ligated to the sticky end left by the RI. P1-barcode ligated DNA from several individuals is then pooled per library, followed by shearing and P2-adaptor ligation. After some clean-ups and an amplification PCR of RADtags, the library can be sequenced.

    In the past, I have always sequenced one RAD-library per HiSeq Illumina lane. Hence, there was no need for me to have an indexed P2-adaptor. However, I'd now like to adopt my protocol for NovaSeq, which means, I need to design several new P2-adaptors each with a unique index. Thus, each library will get its unique index, allowing me to sequence multiple libraries within the same NovaSeq flowcell.
    I was recommended to use the common single-index TruSeq adaptor as a template to construct my new RADseq P2-adaptors. However, RADseq P2-adaptors have some special properties, including a divergent Y-structure. So this makes the design of new P2-adaptors harder.

    Does anyone have indexed P2-RADseq adaptors they have used successfully to construct single-digest RADseq libraries? If so, would you be willing to share the sequences of these P2-adaptors with me? I'd like to have a total of 10 different P2-adaptors (each with a unique index) so that I will be able to multiplex 10 RADseq libraries and sequence them together on a single Novaseq flowcell.

    Thank you a lot for your help!

    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
