  • calculating expected reads

    Hi,

    we are currently trying to decide how to process our 16S amplicons on titanium. How would I come to a rough estimate of expected reads per sample on 1/8th PTP at 16-plex? (assuming everything is perfectly normalized).

    I am under the impression that splitting the plate reduces sequencing output overall but am unsure as to how great a decrease to expect in output to expect.

    Cheers,
    Paul

    Hi,

    The sequencing method manual states that with the 1/8th PTP you could assume 80,000-120,000 reads. That means 5000-7500 reads per sample at 16-plex assuming perfect normalization of the samples.
    Furthermore it says one could expext 450,000-650,000 reads per region when dividing the plate in 2 parts which would result in 900,000-1,300,000 reads per plate. Dividing the plate in 8 parts could yield a maximum of 640,000 - 960,000 reads / plate.

    Best regards,
    Peter

      Hi there,

      The number of reads output for amplicons is less than for shotgun libraries. 1/8th of a PTP should give you 65,000-100,000 HQ reads. A half plate would give 360,000-520,000. These numbers are from Tech Bulletin 13-2009 re: Amplicon Fusion Primer design guidelines.

        Exploring the Dynamics of the Tumor Microenvironment
        by seqadmin




        The complexity of cancer is clearly demonstrated in the diverse ecosystem of the tumor microenvironment (TME). The TME is made up of numerous cell types and its development begins with the changes that happen during oncogenesis. “Genomic mutations, copy number changes, epigenetic alterations, and alternative gene expression occur to varying degrees within the affected tumor cells,” explained Andrea O’Hara, Ph.D., Strategic Technical Specialist at Azenta. “As...

        Exploring Human Diversity Through Large-Scale Omics
        by seqadmin


        In 2003, researchers from the Human Genome Project (HGP) announced the most comprehensive genome to date1. Although the genome wasn’t fully completed until nearly 20 years later2, numerous large-scale projects, such as the International HapMap Project and 1000 Genomes Project, continued the HGP's work, capturing extensive variation and genomic diversity within humans. Recently, newer initiatives have significantly increased in scale and expanded beyond genomics, offering a more detailed...
