title: LAO-A02 2011-01-25 Metagenomic Sequence Data
design: DNA paired-end library was constructed with the AMPure XP/Size Select Buffer Protocol as previously described (1), modified to allow for size-selection of fragments using the double solid phase reversible immobilisation procedure described (2). Size selection yielded metagenomic library fragments with a mean of 450bp. All enzymatic steps in the protocol were performed using the Kapa Library Preparation Kit (Kapa Biosystems) with the addition of 1M PCR-grade betaine in the PCR reaction to aid in amplification of high %G C content templates.  1.
