    Two questions, Miss:

    The RNA trace you showed in other post, is it purified/sizing selected sample or straightly out from amplification reaction?

    What is the amount of your final library?

    THX a lot.

      It is the purified/sizing slected library. I don´t run any chip or gel after the amplification reaction. As I told you before, I follow the protocol as is. The only modification I do is: after shrearing the DNA, I don´t do the ampure cleanup instead I concentrate my sample in a QIAquick column.

      I use the concentration value and avg size I get from the Pico Chip, and throw in some excel spreedsheet I got from Roche years ago. That gives me the number of molec. and the values to make a 10e08 dilution to further dilute and use in the emPCR. Some of the libraries I have sequenced had barely 10e08 molec, so we made emPCR straight out of it and sequencing worked fine.

      The 3kb PE library we sequenced yesterday yield great results, so great I am scared there is something wrong. It was a poor library. I am super curious to see the assembly.

        Oh and as I mentioned before, when I see the peak after nebulization is too low, I proceed with 2 library amplication reaction and combine both in the last purification column step.

          I have a question.
          There is only the amount of 10ng DNA after reaction Plasmid-Safe ATP-Dependent DNase. I'm worried about it is that the experiment failed. Is it that the amount of DNA remaining everybody how much?

            16S/ITS Profiling vs. Shotgun Metagenomics: What Changes in Your Workflow?
            by SEQadmin2




            NGS has revolutionized clinical microbiology by offering new ways to identify and surveil pathogens without prior knowledge of the target. One popular approach is 16S rRNA and ITS amplicon sequencing, which targets specific microbial markers. But studies are increasingly incorporating shotgun metagenomics, a technique that sequences all DNA from a sample without targeting specific microbial markers. This approach allows more detailed taxonomic classification, detection...

            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
