    What indexing should I use?

    I am planning a MiSeq experiment in which I will be doing a PCR mutagenesis of a sequence, with the intention of obtaining just a single mutation in the ~100bp sequence. To do this, I will test 9 different PCR conditions + negative control. The entire sequenced region would be 130-140bp.

    I am having a bit of a hard time thinking about indexing my samples. I am not entirely sure that doing a pair-end run would be very useful. From what I've seen, the majority of primer kits only provide 8 forward primers, and I think I'd need a unique forward and reverse primer in order for the alignment to work. Or, I can do single-sided, which I think would be good enough in my case, but how does it work from a sample preparation point of view - do I just use 10 P7 primers and a single P5 primer for all my samples?

    I am fairly new to NGS and don't know how any of these choices affects data analysis in the later stage.

    Dual Unique Index will not hurt, but single index is enough for MiSeq.

      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.
