产品信息

Incorporating a novel hairpin loop structure, the NEBNext® Adaptor ligates with increased efficiency to end-repaired, dA-tailed DNA. The loop contains a U, which is removed by treatment with USER® Enzyme (a mix of UDG and Endo VIII), to open up the loop and make it available as a substrate for PCR. During PCR, barcodes can be incorporated by use of the NEBNext index primers, thereby enabling multiplexing. This kit includes 96 pre-mixed unique pairs of i5 and i7 index primers, packaged in a single-use 96-well plate with a pierceable foil seal.

NEBNext Oligos can be used with NEBNext products, and with other standard Illumina-compatible library preparation protocols. 

Additional dual barcode options (NEB #E7600, NEB #E7780), and single primer options are also available, in 12- and 96- index formats (NEB #E7335, NEB #E7500, NEB #E7710, NEB #E7730, NEB #E6609). A methylated version of the NEBNext Adaptor is also available for use with bisulfite sequencing protocols (NEB #E7535). 

Workflow:

Designed for use in library prep for DNA, ChIP DNA and RNA (but not Small RNA), the NEBNext Adaptors enable high-efficiency adaptor ligation and high library yields, with minimized adaptor-dimer formation. Incorporating a novel hairpin loop structure, the NEBNext Adaptor ligates with increased efficiency to end-repaired, dA-tailed DNA. The loop contains a U, which is removed by treatment with USER Enzyme (a combination of UDG and Endo VIII), to open up the loop and make it available as a substrate for PCR. During PCR, barcodes can be incorporated by use of the NEBNext index primers, thereby enabling multiplexing. The 96 8-base index primer pairs included in this kit are pre-mixed and are packaged in a single-use 96-well plate with a pierceable foil seal. 

For multiplexing with 384 indices, combine this set with NEB #E6440, NEB #E6442, and NEB #E6446.

16 libraries were prepared with 100 ng of Human NA19240 genomic DNA (Coriell Institute), using the NEBNext Ultra II FS DNA Library Prep Kit (NEB #E7805). Adaptors and primers were from either the IDT® for Illumina –TruSeq® DNA UD Indexes (Illumina #20022370), or the NEBNext Multiplex Oligos for Illumina (96 Unique Dual Index Primer Pairs), NEB #E6440. After 4 PCR cycles, libraries were quantified on an Agilent® TapeStation® 4000.

A) Average library yields for the 8 libraries made using each workflow show 60% higher yield when the NEBNext Adaptor and Unique Dual Index Primer Pairs are used.

B) TapeStation traces of 16 libraries show the presence of adaptor-dimer (indicated by the orange arrow) with the libraries made using IDT for Illumina adaptors and primers, which is absent in the libraries prepared using NEBNext adaptors and primers, which also have higher yields.

96 libraries produced using the NEBNext Ultra II DNA Library Prep Kit (NEB #E7645) and the NEBNext Multiplex Oligos for Illumina (96 Unique Dual Index Primer Pairs Set 3) were pooled at equimolar concentrations and sequenced on the Illumina MiSeq® and NovaSeq® 6000 instruments. The total number of reads from all libraries were summed, and the fraction of the total reads contributed by each library was determined (expected fraction per library = 1.04 %). All 96 libraries clustered efficiently and were represented at approximately the expected frequency on both platforms.

Next® Multiplex Oligos for Illumina® (96 Unique Dual Index Primer Pairs Set 3) |

Human NA19240 genomic DNA (Coriell Institute) was used to prepare 96 libraries using either the NEBNext Ultra II FS DNA Library Prep Kit (NEB #E7805), Covaris-sheared DNA with the NEBNext Ultra II DNA Library Prep Kit (NEB #E7645), or the NEBNext Ultra II DNA Library Prep Kit combined with bisulfite conversion. Universal Human Reference RNA was used to prepare 96 libraries using the NEBNext Ultra II Directional RNA Library Prep Kit (NEB #E7760). Libraries were PCR-amplified using the NEBNext Multiplex Oligos (96 Unique Dual Index Primer Pairs Set 3) to produce libraries containing unique i5 and i7 indices. Library yields were quantified (Agilent® TapeStation® 4200) and normalized by summing the total yield of all 96 libraries and calculating the contribution from each library (expected fraction per library = 1.04%). Library amplification efficiency was robust with each library prep method, and efficiency was uniform across all 96 unique index primer combinations. Each bar represents the average of at least 2 technical replicates.

384 libraries produced using the NEBNext Ultra II DNA Library Prep Kit (NEB #E7645) and the NEBNext Multiplex Oligos for Illumina (96 Unique Dual Index Primer Pairs Set 1-4) were pooled at equimolar concentrations and sequenced on the Illumina NovaSeq® 6000 instrument. The total number of reads from all libraries were summed, and the fraction of the total reads contributed by each library was determined (expected fraction per library = 0.26 %). All 384 libraries clustered efficiently and were represented at approximately the expected frequency.

产品信息

NEBNext Multiplex Oligos for Illumina (Unique Dual Index UMI Adaptors DNA Set 2) are built for more streamlined and informative NGS multiplexing, tracking the sequencing reaction at the individual molecule level and enabling bioinformatic removal of misassigned reads for optimal accuracy. These index adaptors contain a pair of unique dual indices (i5 and i7) and one UMI sequence, making the resulting library multiplex-ready, with or without PCR. This set includes 96 unique dual index UMI adaptors, packaged in a single-use 96-well plate with a pierceable foil seal. The universal primer mix is supplied in a separate vial.

The NEBNext line of Multiplex Oligos can be used with NEBNext sample prep products or other standard Illumina-compatible library preparation protocols. In addition to this set, there are three other sets of NEBNext Unique Dual Index UMI Adaptors for DNA (NEB #E7395, #E7876, #E7878) for multiplexing of up to 384 samples; additional index adaptors with UMIs are available for RNA-seq (NEB #E7416). For multiplexing without UMIs, NEBNext offers several options for added flexibility, including unique dual index primers (NEB #6440, NEB #6442, NEB #E6444, NEB #E6446, and NEB #E6448), dual index primers (NEB #E7600 and NEB #E7780), and single primer sets (in 12- and 96-index formats; NEB #E7335, NEB #E7500, NEB #E7710, NEB #E7730, NEB #E6609), as well as an option compatible with EM-seq™ and bisulfite sequencing (NEB #E7140).

A. Libraries were prepared with 100, 250, and 500 ng inputs of human cell line NA19240 genomic DNA (Coriell Institute for Biomedical Research) and unique dual index adaptors from different suppliers using the NEBNext Ultra™ II FS DNA Library Prep Kit (NEB #E7805) without PCR amplification. The adaptors used were NEBNext Unique Dual Index UMI Adaptrs, xGen® Dual Index UMI Adapters (IDT®) and Nextflex® Unique Dual index Barcodes 1-96 (Bioo Scientific®). Two rounds of SPRIselect bead-based cleanup steps were performed post-ligation, and libraries were quantified by qPCR (NEBNext Library Quant Kit, NEB #E7630).  
B. 90 libraries were prepared with 100 ng NA19240 genomic DNA using the Ultra II FS DNA Library Prep Kit without PCR amplification in a 96-well plate. For the 90 libraries, 30 different adaptors each from NEB, IDT, and Bioo were used for ligation. Libraries were cleaned up and quantitated by qPCR. 
Figure 3. NEBNext Multiplex Oligos for Illumina (Unique Dual Index UMI Adaptors DNA Set 2) allow more-sensitive, low-frequency variant detection.

Next® Multiplex Oligos for Illumina® (Unique Dual Index UMI Adaptors DNA Set 2) |

AcroMetrix® Oncology Hotspot Control DNA (Thermo Scientific®) was used as a mutation DNA source (> 500 mutations with 5-35% allele frequency) and mixed with NA19240 genomic DNA at various ratios to generate a range of allele frequencies (5%-35%, 2.5%-17.5% and 1%-7%). Libraries were constructed using NEBNext Ultra II DNA Library Prep Kit (NEB #E7645) with NEBNext Unique Dual Index UMI Adaptors, and multiplex hybrid capture was performed on all samples using a customized panel for 152 genes from Twist Bioscience®. Libraries were sequenced on a NovaSeq® 6000 (PE140), and reads were downsampled to 110 Million (Seqtk Sample) and mapped to GRCh38 with BWA MEM (0.7.17). Mapped reads were analyzed by MarkDuplicates (Picard 2.20.6) without utilizing UMI information or by building UMI consensus sequences (Fgbio 0.8.1). The final BAM files were used to call somatic variants with Strelka2 (2.9.10).
A. The number of total and correct SNV calls increased when using UMI information for duplicate removal and consensus sequence-based error correction. 
B. The sensitivity of variant detection was improved with UMI consensus calling. The lower the allele frequency, the more benefit provided by UMI information in SNV detection.

Libraries were sequenced on a NovaSeq® 6000 (PE140), and reads were downsampled to 110 Million (Seqtk Sample) and mapped to GRCh38 with BWA MEM (0.7.17). Mapped reads were analyzed by MarkDuplicates (Picard 2.20.6) without utilizing UMI information or by building UMI consensus sequences (Fgbio 0.8.1). The final BAM files were used to call somatic variants with Strelka2 (2.9.10).
A. The number of total and correct SNV calls increased when using UMI information for duplicate removal and consensus sequence-based error correction. 
B. The sensitivity of variant detection was improved with UMI consensus calling. The lower the allele frequency, the more benefit provided by UMI information in SNV detection.

Fig Desc: 96 libraries prepared using the NEBnext Unique Dual Index UMI Adaptors DNA Set 2 and the NEBNext Ultra II FS PCR-free DNA Library Prep Kit (NEB #E6177) were pooled at equimolar concentrations and sequenced on the Illumina MiSeq and NovaSeq 6000 instruments. The total number of reads from all libraries were summed, and the fraction of the total reads contributed by each library was determined (expected faction per library = 1.04%). All 96 libraries clustered efficiently and were represented at approximately the expected frequency on both platforms.
