Product Information

Description

Select your genes from our extensive library! 

Target enrichment, coupled with next generation sequencing (NGS), enables high-throughput, deep sequencing of genomic regions of interest. NEBNext Direct is a novel, hybridization-based capture method offering significant advantages over traditional in-solution hybridization and multiplex PCR protocols.

In the NEBNext Direct target enrichment approach (Figure 1), enzymatically nicked or Covaris® sheared DNA is hybridized to biotinylated oligonucleotide baits that capture both strands of the target DNA and define the 3´ ends of the regions of interest. After hybridization, the bait-target hybrids are bound to streptavidin beads and any 3´ off-target sequence is removed enzymatically. This combination of hybridization with enzymatic removal of 3´ off-target sequence enables greater sequencing specificity relative to conventional hybridization-based enrichment methods. The trimmed targets are then converted into Illumina-compatible libraries that include a 12 bp unique molecular identifier (UMI) in the Illumina i5 index location and an 8 bp sample barcode in the Illumina i7 index location. The NEBNext Direct enrichment method can be performed within one to two days and is compatible with most automated liquid handling instruments.

The NEBNext Direct Custom Ready Panels are designed to enrich for the complete exonic content of genes selected from the Custom Ready portfolio for next generation sequencing on the Illumina platform. This kit contains the oligonucleotides, beads, enzymes and buffers required to convert the desired fragments into a sequence-ready library. Custom Ready Panels are designed for PE150 sequencing.

Figure 2: NEBNext Direct Custom Ready Panels demonstrate optimum performance across a wide range of panel sizes.




Key target enrichment metrics demonstrate consistent performance across a range of panel sizes. 100 ng of DNA was tested against panels of 1, 10, 25, 50 and 100 genes, and sequenced using Illumina paired-end 150 bp sequencing. Larger panels included all genes present in smaller panels.
Figure 3: NEBNext Direct Custom Ready Panels demonstrate retention of target behavior across panel sizes.




IGV image of coverage profile for 4 BRAF exons included in panels of 1, 10, 25, 50 and 100 genes, demonstrate consistent target behavior with the addition of gene targets. 100 ng of DNA was used as input for NEBNext enrichment using the 5 panels, including the BRAF gene. Libraries were sequenced on an Illumina 2 x 150 basepair sequencing.
Figure 4: Sensitivity in detection of variants across panel size and DNA input amount.




24 HapMap samples were blended to create a range of variant allele frequencies (VAF) down to 2%. 25, 50, 100, 200 and 500 ng of this blended DNA was enriched using NEBNext Direct Custom Ready Panels of 1, 10, 25, 50, and 100 genes. Larger panels were inclusive of the genes in smaller panels. Resulting libraries were sequenced using 2 x 150 bp Illumina sequencing and variants were called using Mutect and Vardict variant calling algorithms.

10 ng, 100 ng, and 1 µg of Control DNA was used as input for fragmentation using the NEBNext Direct Nicking Enzyme. Representative electropherograms show fragment sizes compatible with NEBNext Direct enrichment across DNA input amounts.

100 ng of Control DNA was used as input to fragmentation using the NEBNext Direct Nicking Enzyme and Covaris® Shearing. Fragmented DNA was enriched using the 37 kb NEBNext Direct Cancer HotSpot Panel, and sequenced to a mean depth of 3 million reads using Illumina 2 x 75 bp sequencing.
