    ATAC-seq library stability

    I'm just wondering how stable they are after PCR amplification. Recommended storage conditions? How long can the samples survive at room temperature?

    I keep the PCR product in 4 degree after 5xcycles pre-run. After extension cycles, I purified the library and stored them in minus 20 degree. I prefer keep them on ice rather than RT although samples are DNA.

      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...
