    Illumina Multiplexing Primer 2.0

    A collaborator has prepared a custom library for our sequencing by amplifying with the following primers.

    Multiplexing PCR Primer 1.0:
    AATGATACGGCGACCACCGAGATCTACACTCTTTCCCTACACGACGCTCTTCCGATCT

    Multiplexing PCR Primer 2.0:
    GTGACTGGAGTTCAGACGTGTGCTCTTCCGATCT

    I told them the library was not yet ready to sequence because Multiplexing PCR Primer 2.0 does not have a flowcell sequence (which it definitely doesn't). Am I correct that the library is not yet ready to sequence?

    I recognize the primer's name as belonging to an older version of the Illumina-supplied oligo scheme, but am not sure of how the final library was created in that scheme.

    Can someone who used the older scheme let us know if I know what I'm talking about?

    Thank you!

    In the older scheme there was a third indexed primer if I recall.

    Illumina has a primer document that includes even back that far. I would post it here, but they do not want us to post it and they take it down.

    You can ask Illumina for it directly-it is called the "Illumina Customer Sequence Letter" In it are all the sequences-old and new-along with their copyright information. I'm pretty sure that is why they won't post it here. You are agreeing to the copyright by receiving it from them.

      Nine Things a Sample Prep Scientist Thinks About Before Sequencing
      by SEQadmin2


      I’m not a sequencing expert. I’m a purification scientist who uses NGS to evaluate workflows my group develops. With this perspective, we think about the sample first and the NGS workflow second. The sequencer is an exceptionally honest reporter, but it can only report on what you give it, so whether you get clean, interpretable data from an NGS workflow is largely determined before you begin.

      Here are nine questions we think about, in roughly the order they matter, before...

      From Collection to Sequencing: Why Sample Preparation and Preservation Define Sequencing Data
      by SEQadmin2


      Data variability is still an issue in sequencing technologies despite the advances in reproducibility and accuracy of these platforms. But the problem does not originate in the sequencing itself, but in the previous steps, before the sample reaches the sequencer.


      The first step is collection, followed by preservation and sample preparation for analysis. Most scientists overlook those steps, but not being careful might just be skewing the experiment’s results.
