    • NEBNext® Adaptor ligates with increased efficiency to end-repaired, dA-tailed DNA, due to its novel hairpin-loop structure. The loop includes a uracil (U), which is removed by treatment with USER® Enzyme (a mix of UDG and Endo VIII), opening the loop and making it available as a substrate for PCR. During PCR, NEBNext index primers can be incorporated, 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 are for use with NEBNext products or other standard Illumina-compatible library preparation protocols. Additional options are available in unique dual barcodes (NEB #E6440), dual barcode sets (NEB #E7600, NEB #E7780), single primer sets (in 12- and 96- index formats; NEB #E7335, NEB #E7500, NEB #E7710, NEB #E7730, NEB #E6609), and an option compatible with EM-seq™ and bisulfite sequencing (NEB #E7140).Workflow:

      NEBNext Adaptors enable high-efficiency adaptor ligation and high library yields, with minimized adaptor-dimer formation, and are designed for use in library prep for DNA, ChIP DNA and RNA (but not Small RNA). A novel hairpin loop structure ligates with increased efficiency to end-repaired, dA-tailed DNA. The loop contains a U, which is removed by USER Enzyme (a combination of UDG and Endo VIII), thereby becoming a substrate for PCR, when barcodes can be incorporated by use of the NEBNext index primers. 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 withNEB #E6440,NEB #E6444, andNEB #E6446.

      Figure 1: NEBNext Multiplex Oligos for Illumina (96 Unique Dual Index Primer Pairs Set 2) Workflow
      Figure 2: Use of NEBnext Adaptor and Unique Dual Index Primer Pairs substantially increases library yields and minimizes adaptor-dimers
      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.
      Figure 3: Libraries amplified with NEBNext Multiplex Oligos for Illumina (96 Unique Dual Index Primer Pairs Set 2) cluster evenly on the Illumina NovaSeq™ 6000
      96 libraries produced using the NEBNext Ultra II FS DNA Library Prep Kit (NEB #E7805) and the NEBNext Multiplex Oligos for Illumina (96 Unique Dual Index Primer Pairs Set 2) 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.
      Figure 4: NEBNext Multiplex Oligos for Illumina (96 Unique Dual Index Primer Pairs Set 2) amplify libraries with equal efficiency
      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), the NEBNext Enzymatic Methyl-seq (EM-seq) Kit (NEB #E7120), 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 2) 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.
      Figure 5: Libraries amplified with 384 primer pairs from NEBNext Multiplex Oligos for Illumina (96 Unique Dual Index Primer Pairs Set 1-4) cluster evenly on the Illumina NovaSeq™ 6000
      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.
