    Phillip,

    All I know is that gDNA fragments are present in some of my samples, based on the shape of the "inter-region" (I'm trying to attach one of the Bioanalyzer results). I failed to mention that due to the processing of my samples, gDNA is sheared into pieces, so it would show up on the Bioanalyzer graph.
    How did the genomic DNA get sheared?
    Is the hump between the 18S and 28S peaks supposed to be DNA?

      The lysate was passed through QIAshredder columns a couple of times which I believe breaks up the DNA. What that hump is? I am not positive, but according to Agilent in their case it is DNase-sensitive. Page 82 here:

        DNase treatment

        Hello,

        I am using mirVana™ miRNA Isolation Kit, to isolate small RNA from animals blood. Do I have to do DNase treatment for it?

        Thanks,

        Janan

          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...
