    Fragment library preparation for SOLiD 4.0

    Hello, all! We think that we have problems with fragment library
    preparation for SOLiD 4.0. We worked using standard protocol, but
    created library didn't cover whole reference genome. Local FAS, said
    that our problem - is reamplification, but we don't think so.


    Fragment library preparation

    Fragment library preparation

    Starting probe volume: 75 mkl. DNA concentration: 4 mg

    Shearing by Covaris: standard program from manual for SOLiD 4 Library preparation

    End-repear - 30 min (25 degrees)

    After column purification concentration (Quibit – BR) - 60 ng/mkl in 100 mkl

    We divided sample on two probes with same DNA concentration

    After that we worked with one of this probes

    Calculation volume of P1- P2 –adapters - 16, 5 mkl

    Ligation – 15 min (25 degrees)

    Purification on columns

    Size-select (2% agarose)

    Purification on columns after size-select

    DNA-concentration (Quibit – BR) - 72,2 ng/mkl in 50 mkl (3.6 mg)

    LibraryPCR (standard conditions, 3 cycles)

    Purification on columns, DNA-concentration (Quibit – BR) - 30 ng/mkl in 50 mkl (1.5 mg)

    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...
