    Bioanalyzer DNA Smear Analysis

    Hello,

    Does anyone know if smear analysis will ever give a 100% area measurement? I'm trying to figure out my standard error upon detecting two regions; first region starting right after the first marker to 400 bp, second region 400 bp to right before the last marker. I'm measuring A-tailed DNA fragments compared to non A-tailed DNA at increasing concentrations of enzyme, hence increasing blunt-end ligated material. I split the regions in two portions, but they both don't add up to 100%, or will come close at 97-99%.

    Why not just do it by hand in excel using total mass?

      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...
