The Illumina DNA Prep with Enrichment kit is compatible with high-quality, double-stranded genomic DNA (gDNA) inputs of 10–1000 ng or 50-1000 ng FFPE. For human gDNA samples and other large complex genomes, the recommended minimum gDNA input is 50 ng.
The kit uses a bead-based transposome complex to fragment and tag genomic DNA with adaptors followed by a PCR step that adds indexed adapter sequences to the ends of a DNA fragment. After library prep, targets are enriched by hybridizing biotinylated oligonucleotide probes and capturing the targeted library fragments using Streptavidin Magnetic Beads (SMB). The captured, indexed libraries are eluted from the beads and amplified before sequencing.
Use of frozen or clotted blood with the Flex Lysis Reagent Kit and Blood Lysis protocol with Illumina DNA Prep with Enrichment is not supported or tested by Illumina.
The Blood Lysis protocol with Illumina DNA Prep with Enrichment is optimized for the use with K2-EDTA collection tubes (manufactured by Becton Dickinson). Other blood collection tubes may work, but they have not been validated.
Advanced chemistry, optics, and informatics combine to deliver exceptional sequencing speed and data quality, outstanding throughput, and scalability.
