Simplified Workflow for Ultra-High Throughput Sequencing
Twist’s FlexPrepTM UHT Library Preparation Kit offers an NGS alternative to traditional microarray-based technologies for population studies, agrigenomics and other ultra-high throughput applications. Combining Twist’s Normalization by LigationTM (NBL) technology with enzymatic fragmentation methods, the kit offers built-in sample normalization across a wide range of DNA inputs, reducing both cost and complexity of typical sample processing steps. Early sample barcoding enables downstream pooling of twelve separate samples into one reaction for a more streamlined and efficient workflow.

FAQ
The Twist FlexPrepTM UHT Library Preparation Kit takes a novel Normalization by LigationTM approach which eliminates the need for upfront and intermediate sample quantitation, streamlining your sequencing workflow.
Fragmentation and ligation reactions are prepared in one well per sample. The adapters used during ligation contain inline barcodes that allow for the pooling of all 12 wells in a row of a 96-well plate. Individual pools are prepared with indices (UDIs) added by PCR for pool-level demultiplexing. Sequencing throughput can be maximized by running up to 1 152 samples in a single sequencing run from one FlexPrep kit. This increased efficiency can translate to cost and consumables savings.
NGS read depth normalization with variable DNA mass input. Percentage of total read counts identified to each library is calculated after unique dual index and inline barcode demultiplexing. Average with perfect normalization is estimated at 1,04% (100/96).
FlexPrep UHT generates high-complexity libraries that have uniform coverage after target enrichment. In combination with Twist Custom Panels, FlexPrep offers tunable coverage of SNPs, k-mers, structural variants, and other genomic areas of interest. Enriched material was downsampled to an average of 75x coverage. Key target enrichment metrics from Picard are reported.
