For optimal workflow flexibility, NEBNext® Multiplex Oligos are available separately from library preparation kits, providing adaptors and primers for high-yield multiplex Illumina® library production. The NEBNext Adaptor has a unique hairpin loop structure that minimizes adaptor-dimer formation, while NEBNext index PCR primers enable index (barcode) incorporation during library amplification. This third set of unique-dual indices (UDIs) includes 96 pre-mixed unique pairs of index primers (i5 and i7), packaged in a single-use 96-well plate with a pierceable foil seal.
For additional information on available indices and formats for multiplexing, please refer to the NEBNext Multiplex Oligos Selection Chart.
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.
