    Illumina BS-seq library prep query

    Apologies if this has been answered elsewhere, but I've had a glance through the threads and can't see anything obvious.

    I've noted that Illumina's TruSeq kits are incompatible with BS-seq at present because the polymerase mix cannot tolerate uracil. My query is how much of an issue this is to sort out? Is it just a case of finding a different Taq for the library amplification (KAPA do one that seems suitable), or does this also affect the polymerases used to conduct end-repair? What about the polymerases in the SBS chemistry? We'd be wanting to prepare these for a run on a HiScanSQ.

    Thanks,

    Matt

    Publications eg http://www.ncbi.nlm.nih.gov/pubmed/19829295 generally use PhuTurboCx for the library prep PCR - as this replaces the uracils with thymidines the enzyme used in SBS, though I assume there are some tricks with basecalling etc bisulfite-seq due to the base composition imbalance - an experienced service provider should be fine with this though.

      Love this - good data definitely starts from good input, and poor input can only give relatively poor data. I particularly like the mention of Nanodrop/absorbance based methods for quantification. It's such a toss up if you'll get an accurate reading or what amounts to a randomly generated number, and a lot of library/sequencing related issues can be traced back to poor quant.

      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...
