    PCR amplicons primer design - need advice

    Hello,
    I have a list of dna sequences corresponding to a family of HSP proteins in Bacteria (800 seqs of length average 570nt). I would like to design PCR primers for miseq amplification (2*250pb).

    The insert size should be around 460bp since this is the length that is good quality from the miseq sequencing to be analysed.

    I was wondering if you can suggest a pipeline and tools to design my PCR primers that cover most possible species, which are likely to be degenerated.

    My first idea to create an alignment for all sequences using Muscle.

    From there how do i get degenerated primers ?

    Thanks for your comments.

    are you looking for snp's? if so you should be designing your primers to hit a smaller target because you want a lot of overlap in your sequences. Last time I designed primers (it was a while ago) I used ARB-aligned my seqs and used the primer design tool to get potential targets.

    The above is assuming that you've checked lit for other primers hitting your target gene, compiled a list of those, tested in silico against your seqs, and found none appropriate.

    Microbial ecologist, running a sequencing core. I have lots of strong opinions on how to survey communities, pretty sure some are even correct.

      Not looking for SNP , just the HSp proteins that are very conserved across species.

        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.

        Environmental Genomics in the Age of NGS: From Microbes to Conservation Strategies
        by SEQadmin2

        Studying ecosystems means dealing with complex, multi-species communities that are hard to observe at scale. This complexity, however, hides many important questions to be answered, from how biogeochemical cycles work and how climate change can affect species distribution to how conservation strategies can work best.


        Genomics, particularly since the expansion of NGS, has transformed ecosystem ecology. By sequencing environmental DNA, we can now assess biodiversity without direct...
