    SE vs. PE for bacterial RNAseq

    Hello,
    We plan an RNAseq analysis to study gene expression in a bacteria that we have an in house reference genome assembly (~7.8Mbp) and gene annotation (7000 genes) that we are very confident about (both).
    in a previous RNAseq analysis we used 100bp SE reads with ~3M reads per sample (after QC) and got nice coverage and statistics for our gene expression study.

    This time we will use a different service provider (due to some bureaucracy and budget issues) and they offered either ~7-8M reads of 80bp SE, or a similar number of reads but PE with 40bp length and around 350bp insert (for the same price).

    Can anyone suggest me which offer to take ?
    Thank you !

    I would prefer 80bp SE to 40bp PE. I don't think it would have a significant effect on your results, but single-ended reads tend to be easier to work with.

      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
