Homology-based enzymatic DNA fragment assembly-based illumina sequencing library preparation.

ABSTRACT: The current Illumina HiSeq and MiSeq platforms can generate paired-end reads of up to 2 x 250 bp and 2 x 300 bp in length, respectively. These read lengths may be substantially longer than genomic regions of interest when a DNA sequencing library is prepared through a target enrichment-based approach. A sequencing library preparation method has been developed based on the homology-based enzymatic DNA fragment assembly scheme to allow processing of multiple PCR products within a single read. Target sequences were amplified using locus-specific PCR primers with 8 bp tags, and using the tags, homology-based enzymatic DNA assembly was performed with DNA polymerase, T7 exonuclease and T4 DNA ligase. Short PCR amplicons can hence be assembled into a single molecule, along with sequencing adapter
