  • Nextera XT from ds cDNA

    Hi all,

    I made cDNA libaries using the Clontech SMART-Seq v4 ultra low RNA kit and made Nextera XT sequencing libraries from that cDNA. The bioanalyzer result (DNA HS) for the Nextera XT libraries is attached. Obviously Anamenia failed but I'm debating whether the others are OK for pooled sequencing. There is a really large variation in size range. Any input would be very welcome.

    Thanks,
    Kevin

    Technically they can be sequenced. Size variation would be result of variation in input quantity for tagmentation and also bead:library volumes in final clean up. It will be difficult to get similar read number for the libraries. I would suggest to consult with your bioinformatician to see if they can account for unwanted size variation.

      Thanks for the quick reply. For what it's worth, I measured concentration by Qubit and was pretty careful during all steps, especially the clean-up, so I was surprised to see this much variation.

        Strategies for Sequencing Challenging Samples
        by seqadmin


        Despite advancements in sequencing platforms and related sample preparation technologies, certain sample types continue to present significant challenges that can compromise sequencing results. Pedro Echave, Senior Manager of the Global Business Segment at Revvity, explained that the success of a sequencing experiment ultimately depends on the amount and integrity of the nucleic acid template (RNA or DNA) obtained from a sample. “The better the quality of the nucleic acid isolated...
