Experience Faster Library Prep

You’re ready for a DNA library prep and enrichment workflow that’s done before the 8-hour workday ends. See how our library preparation compares in this time-lapse video.

Versatile DNA library prep allows you to examine small, targeted regions or the entire genome.

We’ve combined sample prep and library prep into one easy-to-use product, simplifying the process to create sequence-ready samples. With on-bead fragmentation, no library quantification is needed, which saves you time and increases sequencing data performance by avoiding PCR duplicates.

Simplify Your Workflow with Illumina DNA Prep

Illumina DNA Prep (formerly Nextera DNA Flex) simplifies the upfront DNA fragmentation process and solves other workflow challenges such as DNA extraction, DNA quantification, and library prep QC and library quantification.

DNA Enrichment

Our enrichment library prep yields provides > 90% on-target reads, > 95% uniformity, and low PCR duplicate rate across all Illumina sequencing systems.1 The workflow uses a single, 90-min hybridization step and as little as 10 ng input DNA. On-bead tagmentation chemistry enables support for a wide range of DNA input amounts, various sample types, and a broad range of applications.

Illumina DNA Prep with Enrichment: Simple, Fast, and Flexible

This video overviews the process of selecting the enrichment panel options, the library prep and enrichment workflow for Illumina DNA Prep with Enrichment (formerly Nextera Flex for Enrichment) and data analysis.

Ultra-deep sequencing of amplicons allows efficient variant identification and characterization. Accelerated library prep uses reduced-bias PCR and is gel-free, enabling you to prepare high-quality libraries in less than a day. Mechanical DNA fragmentation and adapter ligation.

Ease-of-use and consistency were the two things that stood out the most. Normalization was spot on. These features are why the [Illumina DNA Prep] is a better choice than the other solutions we have tried.

The Benefits of Tagmentation

Bead-linked transposome tagmentation is an innovative technology used in our library preparation portfolio. On-bead tagmentation lets you get to sequence-ready libraries faster than before by simultaneously fragmenting the gDNA and adding the Illumina sequencing primers. Normalize your library without ancillary reagents or equipment. Reduce turnaround time and complexity.

Understanding Adapter Ligation

The other key technology used in our NGS library prep is adapter ligation, long known for consistent, high-quality data. Libraries are prepared by fragmenting a gDNA or cDNA sample and ligating specialized adapters to both fragment ends. These adapters contain the full complement of sequencing primer hybridization sites. This eliminates the need for additional PCR steps to add the index tag and index primer sites, making the process fully automatable.
