With Nextera technology, DNA is simultaneously fragmented and tagged with sequencing adapters in a single tube enzymatic reaction. Nextera XT supports ultra-low DNA input of only 1 ng. It enables a wide range of input samples, including small genomes, PCR amplicons greater than 300 bp, plasmids, microbial genomes, concatenated amplicons, and double-stranded cDNA.
Multiplexing of up to 384 samples per Nextera XT library is also available for those projects requiring greater throughput. Plus, the kit includes an innovative bead-based sample normalization that eliminates the need for library quantification prior to pooling and sequencing. Libraries prepared with Nextera XT kits are compatible with all Illumina sequencers.
The IDT® for Illumina®-Nextera™ DNA UD Indexes Set A is the latest set of indexes, offering up to 96 unique dual indexes to enable accurate assignment of reads and efficient use of the flow cell.
The IDT for Illumina - Nextera DNA UD Indexes use 10 base pair (bp) index codes. This index code change requires adjustments to the sequencing run setup. See the Nextera DNA UD indexes support page for additional information.

This product is available as an Illumina Advantage (TG) product. Illumina Advantage large-scale sequencing products feature lot-specific shipments and testing, extended shelf life, and advanced change notifications for greater laboratory efficiency.
For high-throughput research, bead-based normalization can save time and resources by providing an accelerated path from DNA to data. This technical note provides guidelines and data comparing the two normalization methods to help you decide which option to use.

The combination of Nextera XT and rapid sequencing with the MiSeq System provides a comprehensive DNA to data workflow in only 8 hours.
The Nextera XT Library Preparation Kit eliminates the need for library quantification before sample pooling and sequencing. Libraries of equivalent concentrations are created by employing bead-based sample normalization, as simple as pipetting 5 μl of each library to be sequenced.
