    "Soft" Nuclear Lysis + PCR (ATAC-SEQ)

    Hi all,

    I am interested in performing ATAC-seq in a confined space. I tagment the nuclei first, then isolate them, and then I want to perform a PCR on these nuclei. However, how would I lyse the nuclei/denature Tn5 without inhibiting the subsequent PCR? Washing inbetween is not an option for us sadly. Do any of you have any tips for this "soft" lysis that does not hamper PCR?

    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...
