    ScriptSeq - 2nd peak @ 550bp

    Hi
    I have been preparing libraries from approx 400ng total RNA, mRNA enrichment, using the ScriptSeqV2 kit.
    At the end I amplify with 12 cycles and I get a profile with a 2nd peak around 550bp. I have not been able to get an explanation for this yet.

    If somebody has an idea I would be grateful.

    Thanks Ferdinand

    P.S. Profile attached.

    Did you quantify the input RNA for the Scriptseq library? The kit works best with 500 pg to 50 ng input.

      No, but assuming that mRNA will never be more than 10% of the total RNA I should be in range.
      Could it be an issue with the fragmentation?

        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...
