Overview

Illumina DNA PCR-Free Prep offers a rapid and flexible workflow for preparing libraries for use in sensitive whole-genome sequencing applications, such as human whole-genome sequencing (WGS), de novo assembly of microbial genomes, and tumor–normal variant calling.

  • Reduces cost by eliminating pre- and post-library quantification steps

  • Provides highly uniform coverage across repetitive or uneven genome regions

  • Delivers fast, automation-compatible workflow in 90 min

Simplify lab operations

The Illumina DNA PCR-Free Prep workflow supports a broad DNA input range, multiple sample types, and both small and large genomes. The workflow includes DNA extraction from blood, saliva, or dried blood spots.

Obtain reliable results

On-bead tagmentation chemistry combined with PCR-free library preparation eliminates PCR-induced bias and diminishes opportunities for error, providing superior and even coverage across high-GC or -AT regions. Learn more about on-bead tagmentation.

Access flexible throughput

The Illumina DNA/RNA UD Indexes Sets offer up to 384 unique dual indexes, enabling accurate assignment of reads and efficient use of the flow cell.

FAQs

PCR-free library preparation is the construction of a DNA library without the use of PCR amplification. Illumina DNA PCR-Free chemistry eliminates PCR-induced bias and provides highly accurate sequence information for sensitive applications.

PCR-free library preparation uses a bead-linked transposome complex to tag genomic DNA by fragmenting and adding adapter tag sequences in a single and rapid reaction step. The single reaction step is called on-bead tagmentation. After the bead-linked transposomes are saturated with DNA, no additional tagmentation can occur, delivering consistent library yield and insert sizes.  Learn more about on-bead tagmentation

 

PCR-free sequencing eliminates PCR amplification steps, significantly reducing typical PCR-induced bias and uneven amplification.

Illumina DNA PCR-Free Prep workflow uses on-bead tagmentation, allowing for consistent insert sizes, uniform coverage, and enhanced performance, regardless of DNA input amount or genome size in a single, rapid reaction. On-bead tagmentation eliminates the need for PCR amplification steps, minimizing biased base composition and opportunities for error, making this kit ideal for sensitive sequencing applications.
