产品信息

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 BRCA1/BRCA2 Panel is designed to enrich for the complete exonic content of the BRCA1 and BRCA2 genes. This kit contains the oligonucleotides, beads, enzymes and buffers required to convert the desired fragments into a sequence-ready library for next-generation sequencing on the Illumina platform and is designed for PE75 or PE150 sequencing.

The NEBNext Direct BRCA1/BRCA2 Panel delivers highly efficient enrichment of BRCA1 and BRCA2 coding regions with a high percentage of reads mapping to targets
Next Direct® BRCA1/BRCA2 Panel |
This histogram shows the percent of reads aligned to the human genome, and the percent of reads mapped to the targets included in the BRCA1/BRCA2 Panel across different input DNA amounts. 10 ng, 100 ng and 1 µg of purified genomic DNA was enriched using the NEBNext Direct BRCA1/BRCA2 Panel. Sequencing reads were generated on an llumina® MiSeq® with 2×75 bp reads, 8 bp Sample ID and 12 bp unique molecular identifier. Sequencing read alignments were performed with BWA-MEM, and PCR duplicates were filtered using the UMIs.

    应用特性

    The NEBNext Direct BRCA1/BRCA2 Panel for Illumina® is designed to enrich for complete exonic content for BRCA1 and BRCA2 genes 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 containing both sample indexes and unique molecular identifiers (UMI). The NEBNext Direct enrichment method can be performed within one day and is easily automated. Each kit component must pass rigorous quality control standards and is lot controlled both individually and as a set of reagents.

    Lot Control: The lots provided in the NEBNext Direct BRCA1/BRCA2 Panel are managed separately and qualified by additional functional validation. Individual reagents undergo standard enzyme activity and quality control assays.

    Functional Validation: Each set of reagents is functionally validated together through construction and sequencing of a target enriched DNA library on an Illumina sequencing platform. For 100 ng of NA19240 DNA input and an average coverage of 100X, 100% of the targets are covered.
