    Is this library double peak due to "DNA Bubble"?

    Hi all,

    I made 48 libraries, most of which meet our expectations, (see 4C) with peak FU at ~ 290bp (library is 170bp insert +121 bp adaptor) with a few that have a mysterious second peak (2A, 4A) in the range of 500-700bp. Is this DNA bubble or something else?

    As mentioned in a previous thread, "Truseq RNA library has 2 peak on bioanalyzer", which according to Illumina does not adversely affect sequencing. Can the same be said for my samples?

    If so, is the DNA bubble an innocuous contaminant to downstream sequencing? If not, what can be done to eliminate the second higher molecular weight peak before I proceed to run my samples on Hi-seq?

    Thanks all,

    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
